Abstract

1516467 Surface wave resonators STANDARD TELEPHONES & CABLE Ltd 29 June 1976 27031/76 Heading H3U A surface wave resonator comprises an interdigital transducer 2 between two interdigital reflecting arrays 3, 4, the bus bars of which are connected in parallel with a variable impedance 9 so that the effective positions of the arrays 3, 4 may be changed and hence the resonant frequency. As shown the impedance 9 is a varactor diode.
