ABSTRACT:
A mechanically tunable ceramic bandpass filter incorporates at least one resonator, the resonator including a resonator body, a coupling capacitor electrically connected to the resonator body, and an electrode pin electrically connected to the coupling capacitor and electrically isolated from the resonator body. A holding bracket fixedly supports the resonator, and is electrically connected to the resonator body. A mechanically deformable tuning tab is fixedly supported and electrically connected to the bracket at a first end. A second end of the tuning tab, variably positioned with the resonator body, forms a variable capacitor for tuning a resonant frequency of the resonator.
