Multi-tapped micro-strip "T" resonator using MEM switch for tuning

In this work we have fabricated multiple MEM (micro-electro-mechanical) switches using a high-T/sub c/ superconductor to change the tap positions (open circuit termination to grounded termination) on a micro-strip "T"-resonator structure. MEM switches at different positions along the base of the "T's" resonator line introduce notches for different operating frequencies. This design has its lowest resonant frequency of approximately 3.5 GHz with the first tap position at the base of the "T"-resonator. The tap positions are changed with three MEM switches placed at the base of the "T"-resonator and separated by 1/8 of the fundamental wavelength. The performance, fabrication details and recent test results will be presented along with simulation data.
