| description | The invention provides a tile-type multi-channel T/R assembly which comprises N channels, each channel comprises a module A and 1/2 modules B, a transmitting branch of the module A comprises a power amplifier chip, an attenuator and a driving amplifier chip, and a receiving branch of the module A comprises a single-pole three-throw switch, an amplitude limiter and a low-noise amplifier chip; the module B is a dual-channel chip and has phase shift and attenuation functions, a power divider divides one path of signal into two paths, and each path comprises a phase shifter, an attenuator and a single-pole double-throw switch chip; and the chip C is a bidirectional amplifier chip and has an amplification function. According to the invention, a multi-chip integration technology and a microwave signal vertical transition technology are adopted, the assembly layout difficulty caused by miniaturization, high density and multi-channel problems of a tile type T/R assembly is solved, the contradiction between the number |
