A Half-Mode Substrate-Integrated-Waveguide Tunable Filter Using Packaged RF MEMS Switches Academic Article

abstract

• A two-pole, half-mode substrate-integrated-waveguide (HMSIW) RF MEMS tunable filter with 28% tuning range around 1.4 GHz is presented. The filter occupies a total area of g 0.7 g @ 1.4 GHz and exhibits an insertion loss of 1.2-3.4 dB, return loss better than 11 dB and quality factor of 75-140 for all tuning states, while having excellent linearity. The filter maintains a constant absolute 1 dB bandwidth of 85 10 MHz over the filter tuning range. Circuit models for the tunable HMSIW resonator and a methodology for systematic filter design are also described in detail. 2012 IEEE.
