Abstract
According to one embodiment, a high frequency amplifier having a division circuit, FET cells, a stabilization circuit and a combination circuit is provided. The division circuit divides an input signal to produce a plurality of signals. The FET cells amplify the signals produced by the division circuit. The stabilization circuit provided with RC parallel-connected circuits which are respectively connected in series between the division circuit and gates of the FET cells. Each of the RC parallel-connected circuits has a capacitor and a resistor connected in parallel with each other. The combination circuit combines the signals amplified by the FET cells.
