    • A device having a radio front end is provided. The radio front end includes an inductor having a first end and a second end. A capacitor having a first end and a second end is connected to the second end of the inductor. An antenna is connected to the second end of the inductor and the second end of the capacitor. A first switch is connected to the first end of the inductor and the first end of the capacitor, wherein the inductor and capacitor form a resonant circuit when the first switch is closed. A second switch is connected to the resonant circuit, the second switch connecting the resonant circuit to ground through a low impedance when the first switch is closed. A third switch is connected to a transmit power amplifier connecting the transmit power amplifier to ground through a low impedance when the first switch is closed.
    • 提供具有无线电前端的设备。 无线电前端包括具有第一端和第二端的电感器。 具有第一端和第二端的电容器连接到电感器的第二端。 天线连接到电感器的第二端和电容器的第二端。 第一开关连接到电感器的第一端和电容器的第一端,其中当第一开关闭合时,电感器和电容器形成谐振电路。 第二开关连接到谐振电路,第二开关在第一开关闭合时通过低阻抗将谐振电路连接到地。 当第一开关闭合时,第三开关连接到通过低阻抗将发射功率放大器接地的发射功率放大器。
