US Patent Issued to Qorvo US on Dec. 9 for "Amplitude modulation-phase modulation (AM-PM) linearization in a power amplifier" (California Inventors)

ALEXANDRIA, Va., Dec. 9 -- United States Patent no. 12,494,745, issued on Dec. 9, was assigned to Qorvo US Inc. (Greensboro, N.C.).

"Amplitude modulation-phase modulation (AM-PM) linearization in a power amplifier" was invented by Baker Scott (San Jose, Calif.) and George Maxim (Saratoga, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Amplitude modulation-phase modulation (AM-PM) linearization in power amplifier techniques are disclosed. In one aspect, a fixed capacitor is placed in parallel to a cascode device within a power amplifier. The sum of capacitances from the cascode device and the parallel capacitor may be relatively fixed across voltage swings, allowing for small phase changes across a wid...
