Abstract
AbstractIn this article, a tunable bandpass filter using micro fixed‐fixed beam structure is designed, simulated, and fabricated. The filter is designed by micromachined capacitive bridges, with an original passive topology. The fabricated filter occupies a chip area of 12 × 3 mm2 and achieved an insertion loss of less than 2 dB and return loss of less than −15 dB throughout the operation band, thereby tuning the filter centre frequency by 11% between 8.76 and 9.8 GHz. © 2010 Wiley Periodicals, Inc.
