    1 dB compression point. It provides a cost effective, more reliable replacement for Traveling Wave Tube (TWT) amplifiers in satellite communications. Comtech EF Data’s extensive experience in the design of outdoor RF transceivers led to the LPOD family’s efficient thermal and mechanical package. Recognizing the evolution of L-Band IF systems, the LPOD is designed to eliminate the traditional requirement for the modem to supply a DC power source and a 10 MHz reference to the BUCs and LNBs.

  • Page 16: Functional Description

    LNB bias T facilitates multi-carrier and redundant operations required of small-to medium-sized hub installations. As shown in Figure 1-1, Comtech EF Data’s LPOD is available in two package styles: the PS-1 model and the PS-2 model. Each LPOD consists of a CEFD SSPA module with the Monitor/Control Processor (MCP), a power supply, and a fan assembly.

  • Page 17: Smart Buc" Functionality

    1.3.4 “Smart BUC” Functionality Comtech EF Data’s unique approach to L-Band/RF frequency conversions eliminates DC and 10 MHz from the input coax. This simplifies redundant and multi-carrier operation. Full 13.75 to 14.5 GHz Ku coverage and 5850 to 6725 MHz C band coverage is offered while supporting industry standard FSK modem/BUC communications, as well as Comtech EF Data proprietary commands.

  • Page 20: Cooling System

    The LPOD contains a robust heat sink and thermal design to maintain a low operating temperature. The LPOD PS-1 contains one fan that is always on, and the LPOD PS-2 contains two temperature-controlled fans that are monitored by the M&C board. The fans draw cool outside air in across the power supply and specialized heat sink.
