Arrangement for transmission/reception improvements in radio communications system with base station has individual transmitter-receivers per antenna in common thermal insulator

摘要

The arrangement has individual transmitter-receiver devices (SEE1-SEE3) for each individual antenna (ANT1-ANT3). The transmitter-receiver devices, which consist at least partly of cryoelectrical components, are mounted in a common thermal insulator for cooling and each has a common transmission-reception band filter, transmission-reception changeover device and preamplifier.
