ABSTRACT:
A high-frequency signal step attenuator including an amplifying circuit having a transistor element with its base or gate connected to an input terminal to which a high-frequency input signal is supplied, and supplying an amplified output signal of the input signal to an output terminal, a current detector for detecting a current flowing through a current path of collector-emitter or a current path of drain-source of the transistor element to generate an output voltage corresponding to a detected current, a voltage setter for selectively generating output voltages of different levels, and a comparator for comparing the output voltage of the current detector with the output voltage of the voltage setter, and supplying an output signal of a compared result as a feedback signal to the base or gate of the transistor element.
