Abstract
A radio frequency front-end includes a first path, second path, and third path each coupled between an antenna and a transceiver. The first path is configured to convey WLAN signals from the transceiver to the antenna for transmission. The second path is configured to convey received Bluetooth signals and received WLAN signals from the antenna to the transceiver. The third path is configured to convey Bluetooth signals from the transceiver to the antenna for transmission when a WLAN link is active and not in a power save state, and is configured to convey received Bluetooth signals from the antenna to the transceiver, and Bluetooth signals from the transceiver to the antenna for transmission, when the WLAN link is either inactive or in the power save state.
