Abstract
A semiconductor chip includes a plurality of transistor rows. Corresponding to the plurality of transistor rows, a first bump connected to a collector of the transistor is arranged, and a second bump connected to an emitter is arranged. The transistor rows are arranged along sides of a convex polygon. A first land and a second land provided in a circuit board are connected to the first bump and the second bump, respectively. A first impedance conversion circuit connects the first land and the signal output terminal. A plurality of transistors in the transistor row are grouped into a plurality of groups, and the first impedance conversion circuit includes a reactance element arranged for each of the groups.
