Patent ID: 6897738

Claim:
A high-frequency switch comprising: a transmission terminal, an antenna terminal, a reception terminal, and a voltage-control terminal; a first diode, the cathode thereof being electrically connected to said transmission terminal, and the anode being electrically connected to said antenna terminal; a first transmission line, electrically connected between said antenna terminal and said reception terminal; a second diode, the cathode thereof being electrically connected to said reception terminal, and the anode being electrically connected to said voltage-control terminal; a second transmission line, one end thereof being electrically connected to said transmission terminal, and the other end being connected to ground; a capacitor, electrically connected between said voltage-control terminal and ground; and a third transmission line, one end thereof being electrically connected to said transmission terminal, and the other end thereof being electrically connected to the antenna terminal; wherein said third transmission line is connected in parallel with the first diode.
