PROBLEM TO BE SOLVED: To provide a small-sized, high-frequency amplifier with a microwave band or a millimeter-wave band.SOLUTION: A parallel-connection high-frequency amplifier 10 includes: semiconductor devices 11, 12; a stabilization circuit 13 to which an input terminal of the semiconductor device is grounded through a resistor 24, a first capacitor 25 and a second capacitor 23 connected in series; and transmission lines 21, 22, 26, 27 each having a predetermined wavelength at a frequency of a high-frequency signal to be amplified. A stabilization resistor of one semiconductor device 11 and a stabilization resistor of the other semiconductor device 12 are shared by the resistor 24.SELECTED DRAWING: Figure 1 |
