摘要：

Conductance measurements are reported on a leaky SAW (LSAW) harmonic one-port resonator on a 64 degrees Y - X LiNbO3 substrate. This employed a short three-finger IDT for fundamental and second harmonic operation together with long reflection gratings. Conductances were measured with and without the end gratings. From an analysis of the measurements, it was deduced that, for optimum second harmonic performance, the grating stopband frequency should be higher than the IDT unperturbed center frequency This result is in contrast to fundamental frequency resonator designs in which the end grating stopband frequency is placed below the IDT center frequency for optimum performance.
