Abstract :
New application of 4-pole SAW component with small losses for the realization of high-frequency voltage-controlled SAW oscillator is described. In contrast to the known circuit solutions of SAW resonators-based oscillators, a new use of radio frequency SAW filter allows to realize the schematic of Colpitts oscillator with noticeably large continuously frequency tuning range than that of counterparts. Proposed oscillator schematic is used to realize digital temperature compensated SAW generator.
