A chilled transceiver for use in terrestrial and satellite communication systems. The chilled transceiver eliminates various problems associated with transceivers which incorporate superconducting devices. In particular, the chilled transceiver is based entirely upon conventional semiconductor technology, such as heterojunction bipolar transistor (HBT) technology formed from conventional GaAs, AlGaAs and InP materials which when chilled to temperatures down to, for example, 100° K can provide a 50% improvement in noise while trimming power losses by 20% or more at the same time. In one embodiment of the invention, the chilled transceiver is formed with a chilled receiver front end which includes a frequency diplexer, a filter, a low-noise amplifier (LNA) and a mixer, formed from conventional semiconductor technology which are housed in a refrigerator typically used for superconducting circuits. Since the receiver front end is formed from conventional semiconductor technology compatibility problems with the balance of the transceiver circuit is eliminated.
