Article Preview

This paper presents a bandpass switchable filter for 6–11GHz applications which is housed in a machined aluminum chassis. The circuit consists of three fixed interdigital microstrip filters and two single-pole triple-throw (SP3T) microelectromechanical systems (MEMS) switching networks achieved by the individual series-shunt MEMS switch chips. A tuning range of 36.6% was achieved from 6.7 to 9.7 GHz with a fractional bandwidth of 21.1±2.7%, with low mid-band insertion loss ranging from 2.6 dB to 3.0 dB. Rejection is below -50 dB in most cases and skirt slopes are more than 50 dB/GHz at both lower and higher stopband.
