Fixed phase difference network device high in integration level and convenient to assemble

A fixed phase difference network device which is high in integration level and convenient to assemble is characterized in that the device is composed of a radio frequency connector and a PCB multi-layer pressing plate, and the radio frequency connector is arranged above the PCB multi-layer pressing plate; the PCB multilayer laminated board comprises a top metal layer, a first dielectric layer, a middle metal layer, a second dielectric layer and a bottom metal layer which are sequentially arranged from top to bottom. According to the fixed phase difference network device with high phase precision, low amplitude fluctuation and high isolation, the power distribution synthesis network and the fixed phase difference network are integrally designed, so that the fixed phase difference network device has the advantages of high integration level and convenience in assembly; in addition, the device has the characteristics of high phase precision, low amplitude fluctuation and high isolation degree by adopting a plural
