ABSTRACT:
A space-based communication system (30), includes a transmission terminal having a transmission antenna (42) and a power amplifier (40) to power the transmission antenna, the power amplifier to generate a power output sufficient to generate an RF signal through the transmission antenna (42), a receive terminal including a receive antenna (45) to receive the RF signal from the transmission terminal and a low noise amplifier (43) to amplify the RF signal channeled through the receive antenna, and a thermoelectric cooler (62) for cooling the low noise amplifier (43) to a predetermined temperature for increasing the sensitivity of the low noise amplifier to minimize the power output generated by the power amplifier required to generate the RF signal thereby minimizing the overall power requirements of the spaced-based communication system (30).
