Mechanical tuning of Superconducting lumped element filter


The tunable filter has variable center frequency (f/sub 0/) and variable bandwidth (BW) that can be adapted to software defined radio. In our mechanical tunable filter, capacitance of each element is changed by motion of dielectric plate that is located above the capacitive elements. The dielectric plates are moved by piezoelectric bimorph actuators. Tuning… (More)
