ABSTRACT:
An amplifier includes: an input terminal configured to have an input signal of a center frequency f0input; a dividing unit that divides the input signal; first through ith blocks configured to have the divided input signal transmitted; a combining unit that combines signals transmitted through the blocks; and an output terminal that outputs the signals combined by the combining unit. The nth block includes a nth former-stage resonator having a fundamental resonant frequency fn, a nth amplifying unit, a nth latter-stage resonator having the fundamental resonant frequency fn, and a nth phase adjusting unit. Each latter-stage resonator having a harmonic resonant frequency either faor fb, satisfies relationship fa<2f1, fb>2f1, (fa+fb)/2=2f0The phase adjusting unit is configured to reverse the phase of signals passing adjacent blocks and maintain all phase differences among signals of 2fnpassing through the nth block in the coordinate-phase.
