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_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.
