2.0–2.7 GHz programmable bandpass filter with RF-MEMS capacitance matrices


A programmable bandpass filter for 2.0–2.7 GHz centre frequencies and 450–500 MHz 3 dB bandwidth is presented. The filter is based on packaged RF-MEMS capacitor matrices as the tunable elements. The coupled-resonator filter topology was chosen with added transfer zeros. The results show excellent match between simulation and measurements. The measured… (More)
