Abstract
A multi-way power amplifier circuit includes two baluns and a number (2×N) of differential power amplifiers, where N≥2. Each balun generates a number (N) of corresponding differential intermediate signal pairs based on a respective to-be-amplified signal. Each differential power amplifier generates a respective differential amplified signal pair based on a respective differential intermediate signal pair. One of the baluns includes: a first transmission line and a second transmission line connected to each other; a number (N) of third transmission lines electromagnetically coupled to the first transmission line; and a number (N) of fourth transmission lines electromagnetically coupled to the second transmission line.
