Abstract
A K-band RF-MEMS uniplanar second-order bandpass filter with
reconfigurable bandwidth is presented. The filter is based on inductively-coupled
half-wavelength slotline resonators and CPW-slotline
multimodal immittance inverters (MIIs). The coupling inductance
and the MII length are reconfigured using RF-MEMS ohmic-contact
switches. Experimental results show a 3 dB relative-bandwidth
change from 4.5 to 8.5% (maintaining a Butterworth response), and
insertion losses of 5.2 and 3.7 dB for either state.
