<p>A high-frequency bias supply circuit (70) includes a plurality of bias supply lines (76A,76B,... 76F) each of which is connected in parallel with others between a corresponding one of selected points along the main signal line (72) and a common bias supply terminal (80). Each of the bias supply lines has a length (L1,L2,... L6) and a distance (B1,B2,... B5) from an adjacent bias supply line different from those of others, the length and the distance being in a range of a 1/8 to 3/8 wavelength of the center frequency. <IMAGE></p> |
