Abstract

This work describes the development of 10‐GHz feedback oscillators with ultra‐low phase noise. Measurement procedures involving injection locking, composition with synchronized sources and vibrational isolation are described. The application is for gravitational waves detectors. The phase‐noise performance obtained was −100 dBc/Hz at 3 kHz, which is still 45 dB worse than the goal performance. © 2009 Wiley Periodicals, Inc.
