Abstract

This paper presents a microwave switchable filter between Band Pass and Band Stop responses. The structure is compact as compared to traditional structures and has no via or DGS in it. The band pass filter uses an interdigital structure and two hairpins attached in a cascaded manner and the band stop filter is designed by shorting finger of the interdigital structure. The band pass filter allows the frequencies from 4.4 to 11.6 GHz and the band stop filter stops the interference of C-Band. This filter is reconfigurable. The filter is reconfigured from one response to another by using a switch. A PN junction diode is used as a switch. This type of filter finds its application where both band pass and band stop filters are required in the same system. To eliminate the high power interference close to the desired signal in a high interference environment, the filter can be used in the band stop mode and in a low interference environment band pass filter is used. So this type of filter can be used to overcome the problem of interference. The structure is designed on FR4 substrate.
