N2 - A group type unidirectional transducer (CHIT) is useful for a low loss SAW filter. The multi-port network expressions for the GUT are presented, and interaction between the inphase(I) and quadrature(Q) electrodes is studied analytically. The conditions for perfect unidirectivity are described. The design procedures of the phase shifters realizing perfect unidirectivity are shown both in series and parallel configurations for any geometrical phase except π.
