Optimization and Realization of a 315-MHz Low-Phase-Noise Voltage-Controlled SAW Oscillator.
IEEE Transactions on Circuits and Systems II: Express Briefs(2012)
Abstract
In this paper, the formulation of QL is derived from the analysis of the Butler common-base surface acoustic wave (SAW) oscillator circuit. The prototype 315-MHz Butler SAW oscillator is designed, and phase-noise results before and after adding voltage-control components are measured. The SAW resonator utilized is R315 with an unloaded quality factor Q0 of about 1.06×104. The measured results of p...
