N2 - A group-type unidirectional SAW transducer with new electrode constitution and new phase shifter has been developed. It is designed to have non-quadratic geometrical phase difference between sending and reflecting electrodes and the electrodes have different finger pairs. In addition, the phase shifter is constituted by only one capacitor and is fabricated on the same piezoelectric substrate. Consequently, inductors of the external network can be reduced. Furthermore, as suppression of backward response is more optimal, the transducer eliminates any adjustment with low loss and low ripple.
