A Novel Tunable Low-pass Filter Based on MEMS and CPW
This paper presents a new type of tunable low-pass filter for millimeter-waves. The filter is based on the slow-wave coplanar waveguide (CPW) lines and tuned by the MEMS capacitive shunt switches. There are 5 switches which can provide two orders of tunable mode. In the first order tuning, the 3dB cutoff frequency changes from 8.2GHz to 10.5GHz, and the second order tuning is 8.2GHz to 16.8GHz. The tested results show that the pass-band ripple is less than 2dB and the maximal out-of-band rejection is better than 20dB. The driven voltages of the switches are around 40V.
