Abstract
An efficient ripple free wide-band single-phase unidirectional SAW transducer is disclosed which requires only a single tuning circuit and a single matching circuit. The unidirectional transducer includes a pair of bidirectional transducers the first of which is connected to a single-phase drive source and the second is connected to a resonant load such that the second transducer acts as a reflecting transducer to cancel out waves traveling in one direction.
