A 200% tuning range of advanced integrated piezoelectric LTCC bandpass filters is presented. The filter incorporates a novel parallel-plate capacitor that can be tuned by a piezoelectrically movable electrode. In this prototype, the fabrication process is modified for better controlling the air-gap inside the capacitor. To our knowledge, the potential… CONTINUE READING
