ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,431,842, issued on Sept. 30, was assigned to Anritsu Co. (Morgan Hill, Calif.).
"Oscillator with phase-noise cancellation" was invented by Oleksandr Chenakin (Morgan Hill, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Circuits, methods, and apparatus that can provide oscillator circuits that have reduced phase noise. An example can provide a yttrium-iron-garnet oscillator in a loop with a loop amplifier and a phase-shift circuit. The yttrium-iron-garnet oscillator can act as a resonator. Quadrature outputs of the yttrium-iron-garnet oscillator can drive a phase detector that can provide a control signal to the phase-shift circuit. The phase-shi...
