Abstract

The invention provides an integrated millimeter wave tile type phased array antenna TR assembly and aims to realize a high integration level. The integrated millimeter wave tile type phased array antenna TR assembly is characterized in that an internal space of a TR assembly module in a Z direction is divided into upper and lower independent expansion spaces, a circuit board (8), a middle metal barrier (3) and a multi-layer circuit board assembly are sequentially integrated between an upper TR assembly assembling body and a lower TR assembly assembling body from up to down, the multi-layer circuit board assembly is distributed with chip sets (6) in a linear array mode, a first multi-layer circuit board is fixedly connected with a groove at a lower portion of a second multi-layer circuit board to form an integrated fixedly-connected assembly, the integrated fixedly-connected assembly is fixedly connected with rectangular bosses at two side edges of the lower assembling body, a large power device is integrated in the lower expansion space close to the lower assembling body, and electrical connection between the two independent expansion spaces is realized through the second multi-layer circuit board.

Description

technical field [0001] The invention relates to a two-dimensional active phased array antenna that can work in satellite communication, radar, guidance and other systems. Its working frequency band is the millimeter wave frequency band, and it supports a tile-type TR component with a single-channel transmission power of several watts. Background technique [0002] With the gradual expansion of the working frequency band to higher frequencies, the system working frequency bands in the fields of communication, radar and guidance are getting higher and higher, and the active phased array antennas in the millimeter wave band have shown very urgent application requirements, especially in vehicle multi- Functional sensors and active protection, satellite communications, precision guidance and other high-mobility and high-value platforms put forward an urgent demand for two-dimensional active phased array antennas in the millimeter wave band. The millimeter-wave two-dimensional act...
