Abstract

Adaptive mode-coupled harmonically tuned voltage-controlled SAW oscillators (VCSOs) are versatile performers in phase-locked reference sources, can be supplied in standard and custom frequencies through 5 GHz at a fraction of the size and power consumption of multiplied references. The typical measured phase noise @ 10 kHz offset from the 5 GHz carrier is -140 dBc/ Hz with 500 kHz tuning and RMS jitter less than 10 femto seconds. To author´s knowledge, the reported 5 GHz VCSO offers about 10 dB superior phase noise performances as compared to commercially available SAW and crystal multiplied sources for a given size, cost, and power-consumptions.
