PROBLEM TO BE SOLVED: To reduce an element area of a pair of MOSFETs while ensuring predetermined pair performance. SOLUTION: In a power amplifier including a pair of MOSFETs 50 each having an active region 14 and a gate electrode 11 having the same profile, the gate electrodes 11 of the paired MOSFETs 10a, 10b are each composed of first portions 11a extending in one direction and second portions 11b extending in another direction crossing the one direction. A plurality of the first portions 11a and a plurality of the second portions 11b are provided, thereby disposing the gate electrodes 11 in matrix. COPYRIGHT: (C)2008,JPO&INPIT
