Abstract

See full text

A drive circuit performs switching between an on-state and an off-state of a PIN diode, the drive circuit being provided with a switching element and a switching element, a drive power supply, and a current limiting resistor that adjusts a forward current of the PIN diode. When the switching element is in an on-state and the switching element is in an off-state, the PIN diode is switched to the on-state by applying a forward voltage to the PIN diode from the drive power supply via the current limiting resistor, and when the switching element is in the off-state and the switching element is in the on-state, the PIN diode is switched to the off-state by applying, not via the current limiting resistor, a reverse voltage to the PIN diode from the drive power supply.
