Abstract:
A power combiner comprising:a plurality of power amplifiers which are even-numbered; a plurality of series-connected branch circuits for respectively distributing input power to said plurality of power amplifiers; and a plurality of series-connected combiners for combining the respective output power of said plurality of power amplifiers; wherein in the case of at least one of such combinations as to equalize electric lengths of transmission lines for connecting between two power amplifiers selected from said plurality of power amplifiers, said combinations each being established by using all of said plurality of power amplifiers once, said electric lengths at which said at least one of the combinations is established, take &lgr;/2i (where &lgr;=wavelength of fundamental wave, and i=positive integer), so as to enable cancellation of at least one harmonic component of odd-order harmonic components.
