Abstract :
This paper presents the development of a low cost switched filter bank module for a wideband software defined radio system. The four-channel switched filter bank module operating in the frequency range of 11~20 GHz has been developed using six single-pole double-throw (SPDT) switching networks, and four fixed five-pole edge-coupled bandpass filters, which is modified from the typical edge-coupled microstrip bandpass filter in the input and output (I/O) feeders to achieve the better stopband performance. The filters and switched filter bank are introduced theoretically and experimentally.
