ABSTRACT:
Provided is a distributed amplification apparatus that outputs an output signal obtained by amplifying an input signal input thereto, comprising an input-side transmission line that transmits the input signal; an output-side transmission line that transmits the output signal; and a plurality of amplifiers that are provided in parallel between the input-side transmission line and the output-side transmission line, the amplifiers each amplifying the input signal transmitted on the input-side transmission line and supplying the amplified signal to the output-side transmission line. Each amplifier includes a transistor; a capacitor provided on a line that transmits the input signal to a gate terminal of the transistor; and a gate-ground resistance that is provided between the gate terminal of the transistor and a ground potential.
