Title:
増幅回路
Document Type and Number:
Japanese Patent JP7154461
Kind Code:
B2
Abstract:
An amplifier circuit is configured in such a way that the amplifier circuit includes: a first amplifier (3) to amplify a signal to be amplified; an output matching circuit (4) through which the signal amplified by the first amplifier (3) propagates; and a second amplifier (7) to amplify the signal which has propagated through the output matching circuit (4), and the output matching circuit (4) is a lumped constant circuit including multiple lumped constant elements, and, by using the multiple lumped constant elements, transforms the impedance seen on the second amplifier (7) side from the first amplifier (3) when the output power of the second amplifier (7) is lower than saturation electric power, to impedance higher than impedance seen on the second amplifier (7) side from the first amplifier (3) when the output power of the second amplifier is equal to the saturation electric power.
