MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647092460 A) filed by Qualcomm Incorporated on July 30, 2026, for Multi-Stage Impedance Tuning In Radio Frequency Transmitter.
Inventors include Inanoglu, Hakan; Spits, Erwin; Metreaud, Leon; and Carrez, Frederic.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: Certain aspects of the present disclosure provide techniques for multi-stage impedance tuning for a radio frequency (RF) transmitter. An example apparatus includes RF circuitry comprising an amplifier, an impedance tuning circuit coupled to an output of the amplifier, and an antenna tuner coupled between an antenna feed and an output of the impedance tuning circuit. The apparatus further includes one or more memories and one or more processors coupled to the one or more memories. The one or more processors are configured to cause the apparatus to configure at least one parameter of the impedance tuning circuit or the amplifier based at least in part on at least one load characteristic at the antenna feed; and communicate one or more signals via the RF circuitry while the at least one parameter is configured based at least in part on the at least one load characteristic at the antenna feed.
