    摘要： Disclosed herein is a power amplifier. The power amplifier includes N power amplification means, a transformer, and a harmonic elimination unit. Each of the N power amplification means amplifies an input signal into a predetermined level. The transformer includes N/2 primary windings respectively connected to the output terminals of the power amplification means and a secondary winding configured such that coil elements are connected in series between an output terminal and a ground, and sums power transmitted from the primary windings. The harmonic elimination unit is disposed across both ends of the secondary winding of the transformer, and eliminates the output of the harmonic frequencies of a preset frequency.
