Abstract : The patent relates to a plurality of electroacoustic stripe electrodes formed as a thin film on the surface of a piezoelectric semiconductor slab. The electrode-semiconductor interface forms a varactor junction. By selectively interconnecting the stripes and applying bias voltages, a tunable electroacoustic transducer of UHF filter is achieved.
