Abstract

A power amplifier device that satisfies both delivering a high output and reducing the chip area occupied by the power amplifier device. Over a substrate, are primary inductors arranged in a generally circular geometry, a ground pattern, transistor pairs, and a secondary inductor. The ground pattern extends from a portion of a region inside the circular primary inductor into regions outside the primary inductor, and grounded at a plurality of points in the regions outside the primary inductor. The primary inductors are coupled to the ground pattern through transistors.
