Abstract
In the letter we propose a phasing and matching network for group-type unidirectional transducers (GT-UDTs) which takes into account the electroacoustic interactions between the two phases of the GT-UDT. In comparison with analogous feed circuits from the literature, this network represents an improvement as far as the reduction of the residual fluctuations in the passband frequency response of a GT-UDT device is concerned.
