Application Research of RF SiP in T / R System

Antenna array is the core equipment of phased array radar system, which includes hundreds of transceiver components. The traditional low-power transceiver channel includes a large number of radio frequency (RF) chips and discrete devices, with complex circuit and low system reliability. RF system in package (SIP) based on advanced micro system technology is especially suitable for phased array radar integration and miniaturization, which is also the key to master the core technology. A self-developed single channel RF transceiver SiP is presented, the important assembly interconnection problems when applied to digital transceiver components is analyzed, the effects of different packaging forms on performance indicators are compared, and the current situation and technical development path of RF SiP for transceiver components are studied.
