초록
The present invention relates to a microwave variable attenuator variably attenuating while maintaining a matching state. The microwave variable attenuator includes: an input terminal for inputting a microwave signal; an output terminal for outputting a microwave signal; a control voltage supplying unit for supplying a control voltage; an input terminal matching unit for matching an impedance of the input terminal in response to the control voltage; an output terminal matching unit for matching an impedance of the output terminal in response to the control voltage; and an attenuating unit for attenuating the microwave signal inputted to the input terminal based on an attenuation controlled according to the control voltage and outputting the attenuated microwave signal, wherein the attenuating unit includes a pin diode and a resonant inductor connected each others in parallel for resonating an effect of a parallel capacitance.
