【 摘 要 】

A novel waveguide passive X-band power limiter with a compact size and simple construction is designed and tested. The proposed limiter is made with the combined structure of a band pass filter and a limiter by incorporating a PIN diode in the narrow gap region of the H-shaped resonant aperture. Single- and two-stage limiters are designed and experimented with. In particular, for the two-stage limiter structure, a miniaturization method is proposed by using an inductor-type iris as a compact inverter, and the limiter length is reduced by about 67%, compared to the conventional one.
