MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617060345 A) filed by Samsung Electronics Co. , Ltd. on May 12, 2026, for Doherty Power Amplifier And Electronic Device Comprising Same.
Inventors include Kang, Hyunuk; Kim, Kyoungtae; Kim, Changwook; Oh, Sungjae; Woo, Youngyoon; and Jee, Seunghoon.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: In embodiments, a two-stage Doherty power amplifier is provided. The two-stage Doherty power amplifier may comprise: a drive amplification circuit; a Doherty amplification circuit including a carrier amplifier and a peaking amplifier; and a network circuit arranged between the drive amplification circuit and the Doherty amplification circuit. The network circuit may comprise: an output matching circuit for the drive amplification circuit; a power distribution circuit for distributing an output of the drive amplification circuit to each of the carrier amplifier and the peaking amplifier; a first input matching circuit for the carrier amplifier; and a second input matching circuit for the peaking amplifier. The power distribution circuit may be configured to provide a phase difference of a specified magnitude in a first direction. Each of the first input matching circuit and the second input matching circuit may be configured to provide the phase difference of the specified magnitude in a second direction opposite to the first direction.
