N2 - In the design of broadband low-loss GUDTs, the effect of bulk wave radiation cannot be neglected. It influences the accurate design of the phasing network for the GUDT, increases the insertion loss and, in addition, the zeros of the frequency response will become less pronounced. In this paper we present the influence of the electrode structure of the GUDT on the cut-off frequency of bulk wave radiation. Furthermore the ratio of bulk wave radiation to surface wave radiation is calculated for a uniform IDT as well as an electrode structure of a GUDT on LiNbO3-128rotYX, LiNbO3-YZ, and Quartz-STX. Finally the effect of bulk wave radiation on the zeros of the frequency response will be shown for several adjustments of the phasing network.
