A band-pass limiting filter (BPLF) based on a microstrip comb line loaded with PIN diodes is proposed in this letter. In contrast to conventional comb line filter designs, the BPLF utilizes PIN diodes to replace capacitor components. When the power of the input signal is below a certain level, the proposed BPLF acts as a filter. While for an input signal whose power is above a certain level, it behaves like a limiter. According to measurement data, the proposed BPLF has a broad passband with an insertion loss of about 3.5 dB from 8.2GHz to 9.0GHz, and a low limiting level of less than 17dBm with a high power input of 50W (47dBm). In general, the proposed BPLF enables dual selectivity of frequency and power, and can be applied to the front end of RF channels.
