| 摘要 |
A high-frequency switch (21) includes a transmission terminal (Tx), an antenna terminal (ANT), a reception terminal (Rx), and a voltage-control terminal (Vc); a first diode (D11), the cathode thereof being electrically connected to the transmission terminal (Tx), and the anode being electrically connected to the antenna terminal (ANT); a first transmission line (13), electrically connected between the antenna terminal (ANT) and the reception terminal (Rx); a second diode (D12), the cathode thereof being electrically connected to the reception terminal (Rx), and the anode being electrically connected to the voltage-control terminal (Vc); a second transmission line (12), one end thereof being electrically connected to the transmission terminal (Tx), and the other end being connected to ground; and a capacitor (C12), electrically connected between the voltage-control terminal (Vc) and ground. The above high-frequency switch can be miniaturized and has superior performance. <IMAGE>
