Thermal Stability of Surface-Acoustic-Wave Devices in the Microwave Band

摘要

Thermal stability of surface-acoustic-wave devices in the microwave band is studied in relation to the thickness and elastic properties of the metal film forming the electrode structure. Thermally stable angles of the singly rotated Y cuts of quartz plates are found for frequencies of 1 and 2 GHz. The dependence of thermal stability on the metallization ratio of the electrode structure is obtained.
