Simulation Study on Coupling of High Power Microwave and RF Module
To address the coupling effect of high-power microwave on integrated circuits,electromagnetic simula-tion software is used to simulate high-power microwave irradiation on a certain type of RF module model.We stud-ied and calculated the coupling signal and electromagnetic distribution of high-power microwaves with frequencies of 1 GHz,3 GHz,and 5 GHz on the RF module.The results showed that as the frequency increased,the current of some capacitors and the voltage of inductors in the RF module also showed an increasing trend.When the HPM fre-quency was close to the center frequency of the antenna in the RF module,the voltage coupled to the antenna port of the chip in the RF module increased.
