Provided in the invention is a highly integrated four-channel T/R assembly. On the basis of the four-channel modular design, the assembly includes four channels. A receiving input terminal (transmitting output terminal) of each transceiving channel is connected in series with a directional coupler to connect a radio-frequency signal; and a receiving output terminal (transmitting input terminal) isconnected in parallel to a quarter power divider and an assembly wave control processing unit. Each transceiving channel includes a multi-function chip 1, a receive signal modulation assembly 2, a transmit signal modulation assembly 3 and a ring blocker 13. The TR assembly has the following advantages: the performance is good; the integration is high; and the design capabilities and key process technologies are broken.
