Quasi-elliptic two pole microstrip filter

A two pole microstrip bandpass filter which has two finite symmetrical transmission zeros is presented. To make extra transmission zeros, a source-load coupling is used. The filter has a center frequency of 3.3 GHz and a fractional bandwidth of 6%. The measured insertion loss is less than 0.35 dB in...

Description
Summary:A two pole microstrip bandpass filter which has two finite symmetrical transmission zeros is presented. To make extra transmission zeros, a source-load coupling is used. The filter has a center frequency of 3.3 GHz and a fractional bandwidth of 6%. The measured insertion loss is less than 0.35 dB in the bandpass.
