This paper presents highperformance RF microelectromechanical systems (RF MEMS) tunable filters with constant absolute bandwidth for the 1.52.5GHz wireless band. The
filter design
is based on corrugated coupled lines and ceramic substrates (εr=9.9) for miniaturization, and the 3bit tuning network is fabricated using a digital/analog RFMEMS device so as to provide a large capacitance ratio and continuous frequency coverage. Narrowband (72 ± 3 MHz) and wideband (115 ± 10 MHz) 1dB bandwidth twopole filters result in a measured
insertion loss
of 1.92.2 dB at 1.52.5 GHz with a power handling of 25 dBm and an IIP3 >> 33 dBm. The filters also showed no distortion when tested under
wideband CDMA
waveforms up to 24.8 dBm. The designs can be scaled to higher dielectricconstant substrates to result in smaller filters. To our knowledge, these filters represent the stateoftheart at this frequency range using any planar tuning technology.
