Patent ID: 8706065

Claim:
A radio frequency (RF) front-end comprising: a first path coupled between an antenna and a transceiver, wherein the first path is configured to convey WLAN signals from the transceiver to the antenna for transmission; a second path coupled between the antenna and the transceiver, wherein the second path is configured to convey received Bluetooth signals and received WLAN signals from the antenna to the transceiver, the second path includes an amplifier coupled between the antenna and a divider, the amplifier (i) is shared by received Bluetooth signals and received WLAN signals and (ii) is configured to output amplified Bluetooth signals and amplified WLAN signals, the amplifier is configured to at least one of (i) be switched off when the second path is not selected, or (ii) pass the received Bluetooth signals and the received WLAN signals without amplification when the second path is selected but no gain is required, and the divider splits the amplified Bluetooth signals and the amplified WLAN signals onto a WLAN receive path and a Bluetooth receive path; and a third path coupled between the antenna and the transceiver, wherein the third path is configured to convey Bluetooth signals from the transceiver to the antenna for transmission when a WLAN link is (i) active and (ii) not in a power save state, and convey (a) received Bluetooth signals from the antenna to the transceiver, and (b) Bluetooth signals from the transceiver to the antenna for transmission, when the WLAN link is either (i) inactive or (ii) in the power save state.
