ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,506,442, issued on Dec. 23, was assigned to Raytheon Co. (Arlington, Va.).
"Offset-mixer interferometric noise suppressed oscillator (INSO)" was invented by James Andrew Dervay (Hudson, Mass.).
According to the abstract* released by the U.S. Patent & Trademark Office: "An offset-mixer INSO provides a fixed phase shift in the reference arm of the interferometric bridge to align the reference arms' variable phase shifter to the mixer's I-channel output and uses the variable phase shifter to amplitude balance the reference and reflection arms. A difference signal between the mixer's Q-channel output and an externally applied carrier frequency tuning voltage VPLL is applied to an amplifi...
