Abstract

This paper proposed a RF-MEMS based dual-band tunable bandpass filter with independently controllable two passbands. The dual-mode resonant is designed to generate independently odd- and even-mode frequency, with RF-MEMS switched network tuning its resonance. Both filter theory and experiment are provided to validate this dual-band tunable filter. The simulation results show that the low passband can be tuned from 2.35 to 2.60GHz, with the 3-dB fractional bandwidth of 10.8%-12.8%, whereas the high passband varies from 3.85 to 4.20GHz with the 3-dB fractional bandwidth of 12.1%-14.7%.
