ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,451,985, issued on Oct. 21, was assigned to KEYSIGHT TECHNOLOGIES INC. (Santa Rosa, Calif.).

"System and method for simulating spurious power of radio frequency (RF) mixer" was invented by Rulon Vandyke (Suwanee, Ga.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Simulating an RF mixer includes mixing input and LO signals at an RF mixer and measuring a mixed output signal, where the input signal has a characterization RF frequency and the LO signal has a characterization LO frequency; determining spurious peak powers and spurious frequencies corresponding to the spurious peak powers of the mixed output signal; specifying a saturation condition of the RF...
