Design and Implementation of a P-band High-power and High-efficiency T/R Module

In order to meet solid-state active phased array radar systems' demand of high radiation power and low power consumption, this paper proposes a design method of P-band T/R modules. Based on modularization, the independent design of transmitting, receiving and control function modules is implemented from the working principle and device selection. In response to the requirement of high power transmission and dual-polarized output, a low-loss and high-power switch is selected to switch polarization, combined with a four-port circulator to ensure efficient switching of receiving/transmitting. A reflection power detection circuit is added to the coupling port of the circulator which further improves the reliability of T/R modules. Compared with traditional P-band T/R modules, the transmitting output power is no less than 332W, and the power added efficiency is no less than 49.5%. The development of the T/R module has a certain impetus to the development of low-frequency solid-state active phased array radar systems.
