Description

technical field

[0001] The invention relates to the technical field of active phased array antennas, in particular to a dual-frequency dual-polarization TR module. Background technique

[0002] Active phased array antenna front-end technology is gradually developing towards dual-frequency compounding and high integration with the improvement of phased array antenna system performance, the development of high-frequency materials and processes, and the advancement of micro-assembly technology. At present, the structure of active phased array antenna mainly includes brick integration and tile integration. The tile active phased array antenna is mostly used in single-frequency single-channel or single-frequency The array antenna can be designed with multi-frequency and multi-channel according to the needs, but the integration level is low, and the volume will be doubled.

[0003] CN210297691U discloses a phased array multi-band TR module, which independently encapsulates the TR...
