    摘要: A power amplifier comprises a plurality of primary inductors provided on a substrate in a circular geometry as a whole; a plurality of amplifier pairs; a secondary inductor; and a connection wiring. Each amplifier pair is coupled to two ends of a corresponding primary inductor, and amplifies and output to the corresponding primary inductor a pair of first and second signals given as differential input signals, respectively. The secondary inductor is provided adjacent to the primary inductors in a circular geometry, further combines and outputs signals made by combining first and second signals in each primary inductor. The connection wiring is provided inside the primary inductors on the substrate and electrically couples middle points of respective primary inductors with each other.
