Abstract: An EMP protection circuit for communication RF front end is designed. It works at 300 kHz-200MHz. The design uses multi-stage PIN diode parallel to form low pass filter network. By establishing time domain model, S parameters of protection circuit are extracted, and thereby the matching network is optimized.
