2.0–2.7 GHz programmable bandpass filter with RF-MEMS capacitance matrices
نویسندگان
چکیده
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 insertion loss is 4.5–5.5 dB over the tuning range, and the linearity measurements show an OIP3 of 55– 64 dBm.
