SATCOM ground terminal RF paths
SATCOM ground terminals place the RF chain between the modem or IF equipment and the antenna system. The path may include up/down conversion, LNA stages, power amplification, filtering, OCXO reference timing, coaxial or waveguide interconnect and antenna-feed hardware.
Where it is used
Fixed earth stations, transportable terminals and vehicle-mounted SATCOM systems use this hardware to maintain uplink and downlink paths under outdoor exposure, cable loss, polarization alignment and thermal variation.
Engineering context
Relevant terminal information includes operating band, link budget, uplink power level, receiver noise, conversion plan, reference stability, feed interface, sealing and grounding. These conditions determine how individual RF modules fit into the terminal path.
