摘要: A combiner for a Doherty amplifier includes, on and in a dielectric substrate, a carrier input terminal, a peak input terminal, an output terminal, a combining point for combining an output signal from the carrier amplifier and an output signal from the peak amplifier, a first λ/4 line connected between the carrier input terminal and the combining point, a second λ/4 line connected between the combining point and the output terminal, and a first directional coupler. The first directional coupler includes a third λ/4 line electromagnetically coupled to one, to be monitored, of the first λ/4 line and the second λ/4 line.

摘要: A synthesizer is constructed by constituting a first λ/4 line of a first strip line and by constituting a second λ/4 line of a second strip line, so that it is formed into a chip shape (or a chip part) in a dielectric substrate. A first shield electrode is formed on the upper face of the dielectric substrate, and a second shield electrode is formed on the lower face of the dielectric substrate, so that the first λ/4 line and the second λ/4 line are formed between the first shield electrode and the second shield electrode.
