Design of Ku-band T/R module based on SIP package

To meet the requirements of Ku-band T/R transceiver module for RF front-end of digital array antenna system, based on the breakthrough of four-channel dual-polarization meta-synthesis architecture design technology, channel high isolation anti-cavity effect design technology, HTCC substrate high-density integration technology, a Ku-band dual polarization high performance T/R module based on SIP package is developed. By designing a microstrip through-the-wall transmission structure to replace the traditional SMP connector, the design of wireless interconnection between radar system modules can be realized, which is beneficial to the system reconfiguration. At the same time, a new type of MEMS ring isolator is designed. The ring isolator is changed from a conventional three-port network to a five-port network, the invention has the advantages of low loss, high power, full shield, high processing precision and good consistency, and can effectively reduce the load traction phenomenon caused by the antenna matching problem, fully ensure the stability of the transceiver link. output power ⩾10W, receiving gain ⩾25dB, noise coefficient ⩽2.5 dB, and good amplitude-phase consistency satisfy systems engineering applications.
