ALEXANDRIA, Va., Feb. 11 -- United States Patent no. 12,549,138, issued on Feb. 10, was assigned to Qorvo US Inc. (Greensboro, N.C.).
"Bandwidth adaptation in a transmission circuit" was invented by Nadim Khlat (Cugnaux, France).
According to the abstract* released by the U.S. Patent & Trademark Office: "Bandwidth adaptation in a transmission circuit is provided. The transmission circuit includes a power amplifier circuit that amplifies a radio frequency (RF) signal based on a modulated voltage, an envelope tracking integrated circuit (ETIC) that generates the modulated voltage based on a modulated target voltage, and a transceiver circuit that generates the RF signal and the modulated target voltage. The RF signal may have a wide modulat...
