Overview
Comtech EF Data’s LPOD-R family of Outdoor Amplifiers / Block Up Converters (BUCs) – referred
to collectively throughout this manual as the LPOD-R – deliver rated power, guaranteed, to the
transmit waveguide flange at the 1 dB compression point. The LPOD-R is a cost-effective
alternative for the LPOD, where the full LPOD’s support of internal 10 M Hz and redundancy is
not required.

Functional Description
The LPOD-R serves as a more reliable replacement for Traveling Wave Tube (TWT) amplifiers in
satellite communications. The compact size and weight of the LPOD-R lends itself to any
installation with limited available mounting space. This includes ship-borne antenna systems,
small “flyaway” systems, and Satellite News Gathering (SNG) installations.
As shown in Figure 1-1, Comtech EF Data’s LPOD-R is available in three models: the PS .5, PS 1,
and PS 1.5. Each LPOD-R consists of a CEFD SSPA module with the Monitor/Control Processor
(MCP), a power supply, and a fan assembly. The amplifier features a Comtech EF Data low loss
combining technique and MCP-based temperature-versus-gain compensation.
