Design of an X-band T/R module with high power

With the development of radar technology, the technology of microwave monolithic integrated circuit is becoming more and more mature. Miniaturized, lightweight, multifunctional millimeter wave radar has been deeply studied and applied at home and abroad. T/R module is the core component of active phased array radar. A high-power T/R component of x-band with four-channels has been studied and designed in this paper. In this paper, a suitable chip carrier is selected to solve the heat dissipation problem caused by the high-power chip through the establishment of heat dissipation model. By embedding the microwave transmission signal in the inner layer, the self-excitation risk is reduced. The partition wall is introduced between the multi-function chip and the driving amplifier or between the driving amplifier and the power amplifier, and the self-excitation problem of the transmitting link is solved.
