ABSTRACT:
A switchable resonator device having a selectable center frequency over a wide radio frequency range comprising a radio frequency signal input and output means, a resonator structure connected between the signal input and output means for respectively receiving and delivering radio frequency input and output signals, the resonator structure using a strip line conductor having a first conductor element with first and second extending portions each providing respective inductance properties, a first switchable means for controllably connecting the first portion of the first conductor element at selected locations along its extension with the second element for varying its inductive properties, a second switchable means for controllably providing a selected capacitance between the second portion of the first conductor element and the second conductor element, and control means providing a control signal to the first and second switchable means for selecting and changing the center frequency of the resonator device at a rapid rate.
