Title: High frequency amplifier circuit
Inventor: OGAWA HIROSHI
IPC: H03F3/193
Filed: 1991-02-27
Abstract: PURPOSE:To realize the high frequency amplifier circuit without overshooting by applying a drain bias voltage to a drain of a FET via at least one diode in the forward polarity. CONSTITUTION:A drain bias voltage is applied to a FET 1 via diodes 4 in forward polarity from a power supply VDD. A capacitor 3 has a sufficiently low impedance with respect to the signal component fed to the FET 1. When a signal whose level is in the vicinity of a saturation input level of a burst shape is applied to the gate of the FET 1, the drain current of the FET 1 is rapidly increased. However, the reduction in the drain bias voltage by the diodes 4 is kept almost constant based on the voltage-current characteristic of the diodes 4. Thus, the fluctuation in the drain bias voltage is suppressed small and a prescribed output signal is obtained and the high frequency amplifier circuit without overshoot is realized.
