US Patent 7535306 Oscillator coupling system

An oscillator coupling system includes a plurality of oscillating members and a plurality of delay members connecting at least two of the oscillating members. Between the delay members is a specific phase or time delay relationship such that characteristics of phase or frequency noise suppression correlation of the two oscillating members are coupled to each other by the delay members, thereby reducing noise autocorrelation while the oscillator coupling system is in operation, enhancing phase or frequency noise suppression, using no bulky elements such as solid state circulators, isolators and resonators, reducing signal distortion, and increasing system stability.
