Abstract
Calculations of the surface acoustic wave (SAW) properties of lead potassium niobate, Pb2KNb5O15, have produced several cuts which are attractive for SAW applications. Each of these cuts possesses a small first‐order temperature coefficient of time delay, a small electromechanical power flow angle, and a large piezoelectric coupling constant. Three cuts have the added attraction of less than isotropic diffraction spreading. The piezoelectric coupling of this material is as much as 17 times as large as it is for ST‐cut quartz, making it attractive for use in temperature‐stable broadband low‐insertion‐loss SAW devices.This publication has 9 references indexed in Scilit:
