Abstract
A power amplifier includes: plural amplifiers; a tournament-tree-shaped circuit connected with the plural amplifiers and including plural transmission lines arranged in a tournament-tree shape; and plural difference frequency short circuits shunt-connected with plural nodes of the tournament-tree-shaped circuit, wherein each of the plural difference frequency short circuits includes an inductor and a capacitor connected in series, resonant frequencies of the plural difference frequency short circuits become lower as the plural difference frequency short circuits are more separated from the plural amplifiers, and the difference frequency short circuits having equivalent resonant frequencies are connected with plural nodes in the same stage among the plural nodes.
