Hybrid SAW oscillators
Abstract
It is pointed out that surface acoustic wave oscillators (SAWOs) have been competing as alternative IF frequency sources to bulk wave crystal oscillators and cavity oscillators for several years and are currently used in numerous military and commercial applications. As a planar element the SAW chip is well suited for an integration into standard hybrid circuits. The fabrication of hybrid SAWOs is reviewed, and results based on two oscillators are presented. Advantages of the considered type of device to microwave systems engineers are related to fundamental frequencies in the range from 20 to 1500 MHz, good frequency stability, ruggedness, FM capability, and small size and low mass.
