Title:
DRIVE CIRCUIT AND IMPEDANCE MATCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/092855
Kind Code:
A1
Abstract:
A drive circuit (A1) performs switching between the on-state and the off-state of a PIN diode (D), said drive circuit being provided with a switching element (SH) and a switching element (SL), a drive power supply, and a current limiting resistor (R) that adjusts a forward current of the PIN diode (D). When the switching element (SH) is in the on-state, and the switching element (SL) is in the off-state, the PIN diode (D) is switched to the on-state by applying a forward voltage to the PIN diode (D) from the drive power supply via the current limiting resistor (R), and when the switching element (SH) is in the off-state, and the switching element (SL) is in the on-state, the PIN diode (D) is switched to the off-state by applying, not via the current limiting resistor (R), a reverse voltage to the PIN diode (D) from the drive power supply.
