ABSTRACT:
An oscillator in which the "tank circuit" or feedback element is a surface acoustic wave (SAW) bandpass filter (delay line). A modulating voltage is applied from end-to-end of the piezoelectric substrate material to provide an incremental change of physical length of the substrate as a function of the modulating voltage. Two sets of interleaved fingers along a surface face of the substrate provide an interdigital arrangement for launching (electrical to acoustic transition) and receiving (acoustic to electrical transition) the surface acoustic wave.
