Abstract

PURPOSE:To obtain a microwave integrated circuit amplifier with excellent characteristic and ease of manufacture by providing an input side directional coupler propagating a feedback current in opposite phase to a reflected wave to the input terminal from an amplifier toward the input terminal. CONSTITUTION:The radio wave from the input terminal 11 is amplified by an amplifier 14 through a directional coupler 12 and outputted from an output terminal 15. In such a case, when a reflected wave comes from the amplifier 14, a reflected wave to the input terminal 11 is generated when the amplifier is matched to obtain low noise, especially. Part of the output wave of the amplifier 14 is fed back to a feedback circuit 16 to propagate the feedback current to the input terminal 11 through the input directional coupler 12, then the reflected wave from the input terminal 11 is cancelled and the feedback current is consumed in a termination resistor 13. Thus, the microwave integrated circuit amplifier while scarcely losing the characteristic is obtained.
