Claim 6:
7. The power amplifier unit according to claim 1, wherein
the tunable harmonic termination circuit further incudes a first terminal and a second terminal between the third input terminal and the third output terminal,
at least one series resonant circuit or at least one parallel resonant circuit, which includes a capacitor and an inductor between the first terminal and the second terminal,
one end of the resonant circuit is connected to a reference potential, and the other end of the resonant circuit is connected to both the third input terminal and the third output terminal of the tunable harmonic termination circuit, and
at least part of the even-ordered harmonic and the odd-ordered harmonic contained in the third radio-frequency signal input to the third input terminal of the tunable harmonic termination circuit is reflected by resonance between the capacitor and the inductor.
