Abstract

See full text

A power amplifier includes: a plurality of FET cells connected in parallel to each other; a plurality of first resistors connected between gate terminals of the plurality of FET cells and grounding terminals respectively; a plurality of second resistors having one ends connected to the gate terminals of the plurality of FET cells respectively and other ends connected to each other; a plurality of capacitors connected in parallel to the plurality of second resistors respectively; and a third resistor connected between a connection point of the other ends of the plurality of second resistors and a power supply terminal, wherein the first resistors have temperature coefficients of resistance greater than those of the second and third resistors and are arranged closer to the corresponding FET cells than the third resistor.
