Abstract
A high-frequency bias supply circuit includes a plurality of bias supply lines each of which is connected in parallel with others between a corresponding one of selected points along the main signal line and a common bias supply terminal. Each of the bias supply lines has a length and a distance from an adjacent bias supply line different from those of others, the length and the distance being in a range of a 1/3 to 3/8 wavelength of the center frequency.
