<p>To obtain a high-frequency switch that allows quick switching from a transmission mode to a reception mode. A high-frequency switch (11) is formed by connecting a first diode (D1) and a second diode (D2) that serve as switching elements, inductors (SL1) and (SL2), capacitors (C5) and (C6), and resistors (R) and (RA). One end of the resistor (RA) is connected between the first diode (D1) and the second diode (D2), and the other end of the resistor (RA) is connected to the ground. Thus, charges accumulated in the diodes (D1) and (D2) in the ON states are immediately released to ground via the resistor. Accordingly, quick switching from the transmission mode to the reception mode by switching of a control power supply terminal (Vc) from ON to OFF is achieved.</p> |
