A compact K-band FDD transceiver front-end

A compact K-band FDD transceiver front-end is implemented using Hybrid Integrated Circuits (HICs) technology. All devices are mounted on Rogers 4350 substrate with low cost Surface Mounted Technology (SMT). The K-band transceiver can transmit 13 dBm and receive -60 dBm to -20 dBm RF signal from 21.2 GHz to 23.6 GHz. With outside duplexer it can operate at full Frequency Division Duplex (FDD) which is very flexible in point-to-point radio communication systems. The whole module is boxed in a 230 mm×100 mm×8.5 mm metal cavity and the whole DC power consumption is only 10.2 Watt.
