Abstract
A convenient prototype of a reconfigurable microwave filter is presented in this paper. The transmission on defined frequencies are achieved by tunable combined lines. The measured performance of a narrow-band reconfigurable band-pass filter is realized using diodes, capacitors, and a voltage sweep of DC feed. Coupling networks in this combline filter enable tuning to be reached with less degradation possible in passband performance. Low passband insertion loss and performance are presented, to show how close they are to theoretical expectation, when the design is adjusted from 0.8 GHz to 1.2 GHz on ADS and Momentum EM Simulator. The frequency range is chosen around 1 GHz in the simulation to predict the filter response on low frequencies used in the next 5G technologies.
