Claim:
1. A traveling-wave amplifier that receives an input signal and generates an output signal derived from the input signal, the traveling-wave amplifier comprising: a semiconductor substrate having a first face; a plurality of amplifier cells provided on the first face of the semiconductor substrate, each of the amplifier cells receiving the input signal and generating a part of the output signal derived from the input signal; an insulating layer provided on the first face of the semiconductor substrate, the insulating layer having a surface on the first face of the semiconductor substrate; an input line provided on the insulating layer in direct contact therewith, the input line being configured to externally receive the input signal at one end thereof and transmit the input signal to respective ones of the amplifier cells, the input line having a first thickness; and an output line provided on the insulating layer in direct contact therewith, the output line being configured to transmit the respective parts of the output signal generated by the amplifier cells and externally output the output signal from one end thereof, the output line having a second thickness larger than the first thickness.
