Abstract

See full text

A traveling-wave amplifier includes a plurality of amplifier cells, an insulating layer, an input line, and an output line. The plurality of amplifier cells is provided on a semiconductor substrate. Each of the amplifier cells receives an input signal and generates a part of an output signal from the input signal. The insulating layer is provided on the semiconductor substrate. The input line is used to externally receive an input signal and to transmit the input signal to the amplifier cells respectively. The output line is used to transmit the output signal generated by the amplifier cells and to externally output the output signal. The thickness of the input line is smaller than the thickness of the output line, and the input line and the output line are provided on the same insulating layer.
