Design and implementation of a Ku-band high gain eight-channel T/R module

A Ku-band high gain eight-channel Transmitter and Receiver(T/R) module is discussed and fabricated with the advantages of highly integrated design of Low Temperature Co-fire Ceramic(LTCC) technologies. The module improves the transmit and receive gains of the component effectively by using bidirectional amplifier. By combining the silicon aluminum shell and the aluminum alloy heat dissipation teeth, the heat conduction ability of the module under continous wave emission conditions is improved greatly. A transmitting power level of 1 W, an emission gain greater than 45 dB, and a receiving gain greater than 29 dB, a receiving circuit noise less than 3.5 dB of the eight-channel T/R module are realized, with a size of 84 mm×48 mm×6 mm, and a low weight of 60 grams. The eight channels of the module have good consistency and stable performance. The module has a good engineering applicability value.
