Abstract
A switch element is arranged between an input terminal and an output terminal. A signal from the input terminal is distributed by a capacitative element and supplied to the cathode side of a diode. An inductor is connected to the cathode side of the diode, and a smoothing circuit including a capacitative element and a resistor is connected to the anode side. The switch element has a control terminal connected to the anode of the diode, and turns off a path between the input terminal and the output terminal when a voltage is applied to the control terminal.
Claims5
A limiter circuit comprising:
- an input terminal to which a high frequency signal is supplied;
- an output terminal to output the high frequency signal supplied to the input terminal;
- a distributor to distribute a portion of the high frequency signal;
- a diode to turn on or off depending on a level and a cycle of the distributed signal, a cathode of the diode connected with the distributor;
- an inductor to ground a current flowing from the diode when the diode is in an on state;
- a smoothing circuit to smooth a voltage generated at an anode of the diode, the smoothing circuit connected between the anode of the diode and a ground;
- and
- a switch element to turn off a path between the input terminal and the output terminal when a voltage is applied to a control terminal, the switch element connected between the input terminal and the output terminal and having the control terminal connected to the anode of the diode.
