According to one embodiment, a limiter includes: a first capacitor and a second capacitor serially connected which are being placed between an input terminal and an output terminal; a semiconductor device connected to a connecting point of the first capacitor and the second capacitor, and to the ground, which becomes conductive when the input terminal receives the high-frequency high-power pulse signal; a choke coil, a first end thereof connected to the connecting point of the first capacitor and the second capacitor; a high-frequency coupler connected to the input terminal; a high-frequency detecting unit connected to the high-frequency coupler to detect the high-frequency high-power pulse signal which is inputted to the input terminal; and a bias applying unit configured to apply a reverse bias voltage to a second end of the choke coil when the high-frequency high-power pulse signal is detected by the high-frequency detecting unit. |
