Abstract
A tunable filter includes a waveguide with at least one resonant cavity and a tunable impedance structure coupled to each resonant cavity. Each resonant cavity has a resonant frequency and its corresponding impedance structure can be tuned to adjust the resonant frequency. The filter transmits the signal in a pass-band that includes the resonant frequency and reflects signals outside the pass-band.
