Abstract
A harmonic processing circuit includes: a feeder line configured to feed power to an amplifying device; and a harmonic processing unit connected to the feeder line, and configured to perform harmonic processing to a harmonic of a signal outputted from the amplifying device. The feeder line is connected to a fundamental wave matching circuit that is connected to the amplifying device and performs matching with respect to a fundamental wave of the signal.
Claims2
A harmonic processing circuit comprising:
- a feeder line configured to feed power to an amplifying device;
- and
- a harmonic processing unit connected to the feeder line, and configured to perform harmonic processing at a harmonic frequency of a signal outputted from the amplifying device, wherein
- the feeder line is connected to a fundamental wave matching circuit that is connected to the amplifying device and performs matching at a fundamental wave frequency of the signal,
- the fundamental wave matching circuit includes a first line having one end connected to the amplifying device, and a second line connected to the other end of the first line,
- the feeder line is connected to a connection portion that connects the first line and the second line, and
- assuming that a wavelength of a fundamental wave of the signal is λ, the first line has a line length not shorter than λ/16 and not longer than 3λ/16.
