Abstract
In a radio frequency amplifier, a resistor and an inductor are connected to a gate terminal of transistor such as an FET. Another resistor for preventing oscillation is connected to the inductor. A capacitor and a third resistor connected to each other in parallel are connected to the first resistor while the other ends thereof are grounded. A resistance value of the resistor for preventing oscillation is in the range of about 30 .OMEGA. to about 70 .OMEGA.. An inductance value of the inductor is such that an impedance value for a low frequency becomes negligibly small.
