Abstract:

A systematic search for zero temperature coefficient of acoustic surface wave delay has been made on the materials, TeO2, quartz, LiTaO3 and LiNbO3. Such temperature compensated orientations are needed for application to wideband multifunction modems and other signal processing devices. Two temperature compensated cuts of TeO2 were discovered. The lowest temperature coefficient of delay on LiTaO3 was found. The 41.5 degree rotated cut, X- propagating orientation of LiNbO3 has a temperature coefficient of delay of 72 ppmdegree C which is the best yet found for this material.
