Highly integrated four-in-one T/R (transmission/reception) assembly

The utility model relates to a highly integrated four-in-one T/R (transmission/reception) assembly, belonging to the technical field of manufacturing of a T/R assembly of a wireless transmission and reception system. The highly integrated four-in-one T/R assembly comprises a shell, a transmission assembly box, a reception assembly box, a transmission assembly, a reception assembly, a control and magnitude/phase monitoring unit and the like. The transmission assembly and the reception assembly are respectively arranged in the transmission assembly box and the reception assembly box, wherein the transmission assembly comprises four preceding power amplifiers, four final-stage power amplifiers, four transmission and reception switches, four broadband filter amplifiers, four low-frequency noise amplifiers, four phase shifters and four isolators; and the reception assembly comprises a reception unit and the control and magnitude/phase monitoring unit. The problem of interference of the strong electromagnetic radiation of the transmission part to the reception part and the control part is solved effectively, the highly integrated four-in-one T/R assembly has good electromagnetic compatibility, and the miniaturization is achieved. When cooling fins are formed on the transmission assembly box through milling, the problem of cooling of the high-frequency and high-power elements of the transmission assembly can be solved. Only six connectors are arranged outside the shell, and the external interfaces have simple structures and can work reliably.
