M80 Hardware Design 4.2. RF output power Table 24: The module conducted RF output power Frequency Max Min GSM850 33dBm ±2dB 5dBm±5dB EGSM900 33dBm ±2dB 5dBm±5dB DCS1800 30dBm ±2dB 0dBm±5dB PCS1900 30dBm ±2dB 0dBm±5dB l e t l c a i e t u n Q fide n o C Note: In GPRS 4 slots TX mode, the max output power is reduced by 2.5dB. This design conforms to the GSM specification as described in section 13.16 of 3GPP TS 51.010-1. 4.3. RF receiving sensitivity Table 25: The module conducted RF receiving sensitivity Frequency Receive sensitivity GSM850 < -108.5dBm EGSM900 < -108.5dBm DCS1800 < -108.5dBm PCS1900 < -108.5dBm 4.4. Operating frequencies Table 26: The module operating frequencies Frequency Receive Transmit ARFCH GSM850 869~894MHz 824~849MHz 128~251 EGSM900 925~960MHz 880~915MHz 0~124， 975~1023 DCS1800 1805~1880MHz 1710~1785MHz 512~885 PCS1900 1930~1990MHz 1850~1910MHz 512~810 4.5. RF cable soldering Soldering the RF cable to RF pad of module correctly will reduce the loss on the path of RF, refer to the following example of RF soldering. M80_HD_V1.0 - 70 -
