Abstract

The invention discloses a dual-frequency dual-polarization TR module which comprises a first radio frequency processing module, a second radio frequency processing module, a first daughter board and a second daughter board. The first radio frequency processing module and the second radio frequency processing module are connected back to back; both the first radio frequency processing module and the second radio frequency processing module carry out airtight processing; the first daughter board is connected below the first radio frequency processing module, the second daughter board is connected below the second radio frequency processing module, the first daughter board is interconnected with the second daughter board, and the first daughter board or the second daughter board accesses power supply and control signals from the bottom; the first radio frequency processing module and the second radio frequency processing module introduce and output radio frequency signals from the longitudinal direction; and the first radio frequency processing module and the second radio frequency processing module respectively comprise a polarization switching chip. According to the invention, the upper and lower cavities of the radio frequency processing link and the low frequency processing line are arranged in a partitioned manner, so that the thickness space is fully utilized, the integration level of the module is improved, and dual-frequency working and polarization switching capabilities are realized.

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...
