This article deals with the design and experimental testing of the ultra low phase noise reflection oscillator incorporating a sapphire whispering gallery resonator (WGR). On a contrast with the conventional loop configuration oscillators with transmission WGR the presented oscillator is based on a reflection WGR excited by a single probe. It is shown that a phase noise of C‐band oscillator of the proposed configuration can be as low as −136 dBc/Hz at 1‐kHz Fourier frequency. © 2007 Wiley Periodicals, Inc.
