Abstract

A 2nd order bandpass filter topology is presented. It employs two single mode ring resonators that coupled via a quarter-wavelength coupled-line to exhibit a pseudo-elliptic bandpass response. The advantage of the topology is that, having only one coupled-line in the structure has reduced the complexity of the circuit to obtain a narrowband response of less than 9% with high rejection level. Prototypes filters were realized to validate the concept using microstrip technology. It was proven that the measurement results had shown good agreement with those from the simulation.
