3. TECHNICAL BRIEF
3.1 General Description
The U250/KU250 supports UMTS-2100, GSM-900, DCS-1800, and PCS-1900 based
GSM/GPRS/UMTS. All receivers and the UMTS transmitter use the radio One1Zero-IF architecture to
eliminate intermediate frequencies, directly converting signals between RF and baseband. The quadband GSM transmitters use a baseband-to-IF upconversion followed by an offset phase-locked loop
that translates the GMSK-modulated signal to RF.

3. TECHNICAL BRIEF
A generic, high-level functional block diagram of U250/KU250 is shown in Figure 1-1. One antenna
collects base station forward link signals and radiates handset reverse link signals. The antenna
connects with receive and transmit paths through a FEM(Front End Module).
The UMTS receive path each include a LNA, a RF band-pass filter, and a downconverter that translate
the signal directly from RF-to-baseband using radioOne ZIF technique. The RFIC Rx analog baseband
outputs, for the receive chains, connect to the MSM IC. The UMTS and GSM Rx baseband outputs
share the same inputs to the MSM IC.
For the transmit chains, the RTR6275 IC directly translates the Tx baseband signals (from the MSM
device) to an RF signal using an internal LO generated by integrated on-chip PLL and VCO. The
RTR6275 IC outputs deliver fairly high-level RF signals that are first filtered by Tx SAWs and then
amplified by their respective UMTS PA. The high- and low-band UMTS RF transmit signals emerge
from the RTR6275 transceiver.
In the GSM receive paths, the received RF signals are applied through their band-pass filters and
down-converted directly to baseband in the RTR6275 transceiver IC. These baseband outputs are
shared with the UMTS receiver and routed to the MSM IC for further signal processing.
The GSM transmit paths employ one stage of up-conversion and, in order to improve efficiency.
1. The on-chip quadrature up-converter translates the GMSK-modulated signal to a constant envelope
phase signal at RF;
2. The amplitude-modulated (AM) component is applied to the ramping control pin of power amplifier
from a DAC within the MSM
U250/KU250 power supply voltages are managed and regulated by the PM6650 Power Management
IC. This versatile device integrates all wireless handset power management, general housekeeping,
and user interface support functions into a single mixed signal IC. It monitors and controls the external
power source and coordinates battery recharging while maintaining the handset supply voltages using
low dropout, programmable regulators.
The device’s general housekeeping functions include an ADC and analog multiplexer circuit for
monitoring on-chip voltage sources, charging status, and current flow, as well as userdefined off-chip
variables such as temperature, RF output power, and battery ID. Various oscillator, clock, and counter
circuits support IC and higher-level handset functions. Key parameters such as under-voltage lockout
and crystal oscillator signal presence are monitored to protect against detrimental conditions.

3.2 GSM Mode
3.2.1 GSM Receiver
The Dual-mode U250/KU250’s receiver functions are split among the three RFIC’s as follows:
• GSM-900, DCS-1800, and PCS-1900 UMTS-2100 modes use the RTR6275 IC only. Each mode has
independent front-end circuits and down-converters, but they share common baseband circuits (with
only one mode active at a time). All receiver control functions are beginning with SBI2-controlled
parameters.
RF Front end consists of antenna, antenna switch module(D5011) which includes three RX saw
filters(GSM900, DCS and PCS). The antenna switch module allows multiple operating bands and
modes to share the same antenna. In U250/KU250, a common antenna connects to one of six paths:
1) UMTS-2100 Rx/Tx, 2) GSM-900 Rx, 3) GSM-900 Tx, 4) DCS-1800 Rx, and 5) DCS-1800 Tx, PCS1900 Tx(High Band Tx’s share the same path), 6) PCS-1900 Rx. UMTS operation requires
simultaneous reception and transmission, so the UMTS Rx/Tx connection is routed to a duplexer that
separates receive and transmit signals. The GSM900, DCS, and PCS operation is time division
duplexed, so only the receiver or transmitter is active at any time and a frequency duplexer is not
required.

The RFIC operating modes and circuit parameters are MSM-controlled through the proprietary 3-line Serial Bus Interface (SBI). The Application
Programming Interface (API) is used to implement SBI commands. The API is documented in AMSS Software - please see applicable AMSS
Software documentation for details.

3. TECHNICAL BRIEF
The GSM900, DCS, and PCS receiver inputs of RTR6275 are connected directly to the transceiver
front-end circuits(filters and antenna switch module). The GSM900, DCS, and PCS receiver inputs use
differential configurations to improve common-mode rejection and second-order non-linearity
performance. The balance between the complementary signals is critical and must be maintained from
the RF filter outputs all the way into the IC pins
Since GSM900, DCS, and PCS signals are time-division duplex (the handset can only receive or
transmit at one time), switches are used to separate Rx and Tx signals in place of frequency duplexers this is accomplished in the switch module.
The GSM900, DCS, and PCS receive signals are routed to the RTR6275 through band selection filters
and matching networks that transform single-ended 50-Ω sources to differential impedances optimized
for gain and noise figure. The RTR input uses a differential configuration to improve second-order intermodulation and common mode rejection performance. The RTR6275 input stages include MSMcontrolled gain adjustments that maximize receiver dynamic range.
The amplifier outputs drive the RF ports of the quadrature RF-to-baseband downconverters.
The downconverted baseband outputs are multiplexed and routed to lowpass filters (one I and one Q)
having passband and stopband characteristics suitable for GMSK processing. These filter circuits
include DC offset corrections. The filter outputs are buffered and passed on to the MSM6245 IC for
further processing (an interface shared with the RFR6275 UMTS receiver outputs).

3.2.2 GSM Transmitter
The RTR6275 transmitter outputs(DA_HB2_OUT and DA_LB1_OUT)include on-chip output matching
inductors. The 50ohm output impedance is achieved by adding a series capacitor at the output pins.
The capacitor value may be optimized for specific applications and PCB characteristics based on passband symmetry about the band center frequency, the suggested starting value is shown in Figure1.3.

The RTR6275 IC is able to support GSM 900 and GSM 1800/1900 mode transmitting. This design
guideline shows a tri-band GSM application.
Both high-band and low band outputs are followed by resistive pads to ensure that the load presented
to the outputs remains close to 50ohm. The low-band GSM Tx path also includes a Tx-band SAW filter
to remove noise-spurious components and noise that would be amplified by the PA and appear in the
GSM Rx band

3. TECHNICAL BRIEF
3.3 UMTS Mode
3.3.1 Receiver
The UMTS duplexer receiver output is routed to LNA circuits within the RTR6275 device. The UMTS Rx
input is provided with an on-chip LNA that amplifies the signal before a second stage filter that provides
differential downconverter. This second stage input is configured differentially to optimize second-order
intermodulation and common mode rejection performance. The gain of the UMTS frontend amplifier and
the UMTS second stage differential amplifier are adjustable, under MSM control, to extend the dynamic
range of the receivers. The second stage UMTS Rx amplifiers drive the RF ports of the quadrature RFtobaseband downconverters. The downconverted UMTS Rx baseband outputs are routed to lowpass
filters having passband and stopband characteristics suitable for UMTS Rx processing. These filter
circuits allow DC offset corrections, and their differential outputs are buffered to interface shared with
GSM Rx to the MSM IC. The UMTS baseband outputs are turned off when the RTR6275 is
downconverting GSM signals and on when the UMTS is operating.
3.3.2 Transmitter
The UMTS Tx path begins with differential baseband signals (I and Q) from the MSM device. These
analog input signals are amplified, filtered, and applied to the quadrature up-converter mixers. The upconverter output is amplified by multiple variable gain stages that provide transmit AGC control. The
AGC output is filtered and applied to the driver amplifier; this output stage includes an integrated
matching inductor that simplifies the external matching network to a single series capacitor to achieve
the desired 50-Ω interface.
The RTR6275 UMTS output is routed to its power amplifier through a bandpass filter, and delivers fairly
high-level signals that are filtered and applied to the PA. Transmit power is delivered from the duplexer
to the antenna through the switch module. The transceiver LO synthesizer is contained within the
RTR6275 IC with the exception of the off-chip loop filter components and the VC-TCXO. This provides
a simplified design for multimode applications. The PLL circuits include a reference divider, phase
detector, charge pump, feedback divider, and digital logic generator.
UMTS Tx using PLL1, the LO generation and distribution circuits create the necessary LO signals for
different frequency converters. The UMTS transmitter also employs the ZIF architecture to translate the
signal directly from baseband to RF. This requires FLO to equal FRF, and the RTR6275 IC design
achieves this without allowing FVCO to equal FRF.
The RTR6275 IC is able to support UMTS 2100/1900 and UMTS 850 mode transmitting. This design
guideline shows only UMTS 2100 applications.

3. TECHNICAL BRIEF
3.4 LO generation and distribution circuits
The integrated LO generation and distribution circuits are driven by internal VCOs to support various
modes to yield highly flexible quadrature LO outputs that drive all GSM and UMTS band upconverters
and downconverters; with the help of these LO generation and distribution circuits, zero-IF architecture
is employed in all GSM and UMTS band receivers and transmitters to translate the signal directly from
RF to baseband and from baseband to RF.
Two fully functional fractional-N synthesizers, including VCOs and loop filters, are integrated within the
RTR6275 IC. The first synthesizer (PLL1) creates the transceiver LOs that support the UMTS
2100/1900/1800 transmitter, and all four GSM band receivers and transmitters including: GSM 850,
GSM 900, GSM 1800, and GSM 1900. The second synthesizer (PLL2) provides the LO for the UMTS
2100/1900/1800 receiver. An external TCXO input signal is required to provide the synthesizer
frequency reference to which the PLL is phase and frequency locked. The RTR6275 IC integrates
most of PLL loop filter components on-chip except two off-chip loop filter series capacitors, and
significantly reduces off-chip component requirement. With the integrated fractional-N PLL
synthesizers, the RTR6275 has the advantages of more flexible loop bandwidth control, fast lock time,
and low-integrated phase error

3.5.2 VCTCXO (X100 : DSA321SCE-19.2M)
The Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) provides the
reference frequency for all RFIC synthesizers as well as clock generation functions within the
MSM6245 IC. The oscillator frequency is controlled by the MSM6245 IC.
TRK_LO_ADJ pulse density modulated signal in the same manner as the transmit gain control
TX_AGC_ADJ. A two-pole RC lowpass filter is recommended on this control line.
The PM6650 IC controls the handset power-up sequence, including a special VCTCXO warm-up
interval before other circuits are turned on. This warm-up interval (as well as other TCXO controller
functions) is enabled by the MSM TCXO_EN line . The PM6650 IC VREG_TCXO regulated output
voltage is used to power the VCTCXO and is enabled before most other regulated outputs.
Any GSM mode power control circuits within the MSM6245 IC require a reference voltage for proper
operation and sufficient accuracy. Connecting the PM6650 IC REF_OUT directly to the MSM6245 IC
GSM_PA_PWR_CTL_REF provides this reference. This sensitive analog signal needs a 0.1 •ÏF low
frequency filter near to MSM side, and isolate from digital logic and clock traces with ground on both
sides, plus ground above and below if routed on internal layers.
3.5.3 Front-End Module (U500 : D5011)
This equipment uses a single antenna to support all handset operating modes, with an antenna switch
module select the operating frequency and band. UMTS operation requires simultaneous reception
and transmission, so the UMTS Rx/Tx connection is routed to a duplexer that separates receive and
transmit signals. The active connection is MSM-selected by three control lines (GPIO[9], GPIO[10]).
Two GPIO are programmed to be ANT_SEL0_N, ANT_SEL1_N) respectively.

The SKY77318 is an extremely small (6 x 6 mm), GSM PAM for handset applications. This module
has been optimized for excellent efficiency and Pout while maintaining high GSM/GPRS efficiency.
The small size and high performance is achieved with high-reliability GaAs HBT technology.

3. TECHNICAL BRIEF
3.5.6 UMTS Duplexer(FL104:ACMD-7602)
A UMTS duplexer splits a single operating band into receive and transmit paths. Important
performance requirements include;
• Insertion loss. this component is also in the receive and transmit paths ; In the U250/KU250 typical
losses : UMTS2100_ Tx = 1.2 dB, UMTS2100_ Rx = 1.4 dB
• Out-of-band rejection or attenuation. the duplexer provides input selectivity for the receiver, output
filtering for the transmitter, and isolation between the two. Rejection levels for both paths are
specified over a number of frequency ranges. Two Tx-to-Rx isolation levels are critical to receiver
performance:
• Rx-band isolation. the transmitter is specified for out-of-band noise falling into the Rx band. This
noise leaks from the transmit path into the receive path, and must be limited to avoid degrading
receiver sensitivity. The required Rx-band isolation depends on the PA out of-band noise levels and
Rx-band losses between the PA and LNA. Minimum duplexer Rx band isolation value is about 51 dB.
• Tx-band isolation. the transmit channel power also leaks into the receiver. In this case, the leakage is
outside the receiver passband but at a relatively high level. It combines with Rx band jammers to
create cross-modulation products that fall in-band to desensitize the receiver. The required Tx-band
isolation depends on the PA channel power and Tx-band losses between the PA and LNA. Minimum
duplexer Tx-band isolation value is about 58dB.
• Passband ripple. the loss of this fairly narrowband device is not flat across its passband. Passband
ripple increases the receive or transmit insertion loss at specific frequencies, creating performance
variations across the band.s channels, and should be controlled.
• Return loss. minimize mismatch losses with typical return losses of 10 dB or more (VSWR <2:1).
• Power handling. high power levels in the transmit path must be accommodated without degraded
performance. The specified level depends on the operating band class and mobile station class (per
the applicable standard), as well as circuit losses and antenna EIRP. Several duplexer characteristics
depend upon its source and load impedances. QUALCOMM strongly recommends an isolator be
used between the UMTS PA and duplexer to assure proper performance.

3. TECHNICAL BRIEF
3.5.7 UMTS Rx RF filter (FL103 : EFCH2140TDE1)
• Frequency range : 2110 ~ 2170MHz
An RF filter is located between the UMTS LNA and mixer. Insertion loss is important, but not as
critical as losses before the LNA. The most important parameters of this component include:
• Out-of-band rejection or attenuation levels, usually specified to meet these conditions:
- FFar out-of-band signals - ranging from DC up to the first band of particular concern and from the
last band of particular concern to beyond three times the highest passband frequency.
- Tx-band leakage - the transmitter channel power, although attenuated by the duplexer, still
presents a cross-modulation threat in combination with Rx-band jammers. The RF filter must
provide rejection of this Tx-band leakage.
- Other frequencies of particular concern . bands known to include other wireless transmitters that
may deliver significant power levels to the receiver input.

3. TECHNICAL BRIEF
3.8.10. Stereo Wideband CODEC
The MSM6245 device integrates a wideband voice/audio CODEC into the mobile station modem
(MSM). The CODEC supports two differential microphone inputs, one differential earphone output, one
single-ended earphone output, and a differential analog auxiliary interface.
The CODEC integrates the microphone and earphone amplifiers into the MSM6245 device, reducing
the external component count to just a few passive components.
The microphone (Tx) audio path consists of a two-stage amplifier with the gain of the second stage set
externally. The Rx/Tx paths are designed to meet the ITU-G.712 requirements for digital transmission
systems.
3.8.11. Vocoder Subsystem
The MSM6245 device’s QDSP4000 supports AMR,FR,EFR and HR. In addition, the QDSP4000 has
modules to support DTMF tone generation, DTMF tone detection, Tx/Rx volume controls, Tx/Rx
automatic gain control (AGC), Rx Automatic Volume Control (AVC), ear seal echo canceller (ESEC),
Acoustic Echo Canceller (AEC), Noise Suppression (NS), and programmable, 13-tap, Type-I, FIR,
Tx/Rx compensation filters. The MSM6245 device’s integrated ARM9TDMI processor downloads the
firmware into the QDSP4000 and configures QDSP4000 to support the desired functionality.
3.8.12. ARM Microprocessor subsystem
The MSM6245 device uses an embedded ARM926EJ-S microprocessor. This microprocessor,
through the system software, controls most of the functionality for the MSM device, including control of
the external peripherals such as the keypad, LCD, RAM, ROM, and EEPROM devices. Through a
generic single serial bus interface (SSBI) the ARM926EJ-S configures and controls the functionality of
the RFR6275, RTR6275, and PM6650 devices.
3.8.13. Mode Select and JTAG Interfaces
The mode pins to the MSM6245 device determine the overall operating mode of the ASIC. The options
under the control of the mode inputs are Native mode, which is the normal subscriber unit operation,
ETM mode, which enables the built-in trace mode, and test mode for factory testing. The MSM6245
device meets the intent of the ANSI/IEEE 1149.1A-1993 feature list. The JTAG interface can be used
to test digital interconnects between devices within the mobile station during manufacture.

3. TECHNICAL BRIEF
3.8.14. General-Purpose Input/Output Interface
The MSM62450 device has general-purpose bidirectional input/output pins. Some of the GPIO pins
have alternate functions supported on them. The alternate functions include USB interface, additional
RAM, ROM, general-purpose chip selects, parallel LCD interface, and a UART interface. The function
of these pins is documented in the various software releases.
3.8.15. UART
The MSM6245 device employs three UARTs. UART1 has dedicated pins while UART2 and UART3
share multiplexed pins.
3.8.16. USB
The MSM6245 device integrates a universal serial bus (USB) controller that supports both
unidirectional and bidirectional transceiver interfaces. The USB controller acts as a USB peripheral
communicating with the USB host. MSM6245 supports the 3-wire functionality.

3. TECHNICAL BRIEF
3.9 Power Block
3.9.1. General
MSM6245, included RF, is fully covered by PM6650(Qualcomm PMIC). PM6650 cover the power of
MSM6245, MSM memory, RF block, Bluetooth, USIM and TCXO. Major power components are :
3.9.2. PM6650
The PM6650 device (Figure 1-1) integrates all wireless handset power management. The power
management portion accepts power from all the most common sources - battery, external charger,
adapter, coin cell back-up - and generates all the regulated voltages needed to power the appropriate
handset electronics. It monitors and controls the power sources, detecting which sources are applied,
verifying that they are within acceptable operational limits, and coordinates battery and coin cell
recharging while maintaining the handset electronics supply voltages.
Eight programmable output voltages are generated using low dropout voltage regulators, all derived
from a common trimmed voltage reference. A dedicated controller manages the TCXO warm-up and
signal buffering, and key parameters (under-voltage lockout and crystal oscillator signal presence) are
monitored to protect against detrimental conditions.
MSM device controls and statuses the PM6650 IC using Single Serial Bus Interface (SSBI)
supplemented by an Interrupt Manager for time-critical information. Another dedicated IC Interface
circuit monitors multiple trigger events and controls the power-on sequence.

3.9.3. Charging control
A programmable charging block in PM6650 is used for battery charging. It is possible to set limits for
the charging current. The external supply typically connects directly to pin (VCHG). The voltage on this
pin (VCHG) is monitored by detection circuitry to ascertain whether a valid external supply is applied or
not. For additional accuracy or to capture variations over time, this voltage is routed internally to the
housekeeping ADC via the analog multiplexer. PM6650 circuits monitor voltages at VCHARGER and
ICHARGE pins to determine which supply should be used and when to switch between the two
supplies. These pins are connected to the Source (or emitter) and Drain (or collector) contacts of the
pass transistor respectively.

3. TECHNICAL BRIEF
3.11.8.1. Audio Signal Processing & Interface
Audio signal processing is divided uplink path and downlink path. The uplink path amplifies the audio
signal from MIC and converts this analog signal to digital signal and then transmits it to DBB Chip
(MSM6245). This transmitted signal is reformed to fit in GSM & WCDMA frame format and delivered to
RF Chipset. The downlink path amplifies the signal from DBB chip (MSM6245) and outputs it to
receiver (or speaker).
The receive path can be directed to either one of two earphone amplifiers or the auxiliary output. The
outputs earphone1 (EAR1OP, EAR1ON) and auxiliary out (LINE_P, LINE_N) are differential outputs.
Earphone2 (HPH_L, HPH_R) is a single-ended output stage designed to drive a headset speaker.
The microphone interface consists of two differential microphone inputs, one differential auxiliary input
and a two-stage audio amplifier.
