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.
