Abstract:
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.
