Abstract:
1. A radio frequency (RF) front-end configured to share transmissions and receptions of Bluetooth signals and WLAN signals, the RF front-end comprising: a first path coupled between an antenna and a transceiver, the first path dedicated to transmissions of the WLAN signals; a second path coupled between the antenna and the transceiver, the second path dedicated to simultaneous receptions of the Bluetooth signals and the WLAN signals, wherein: a third path coupled between the antenna and the transceiver, the third path dedicated to: a switch coupled between to the antenna and the first path, the second path, and the third path to control which of the first path, the second path, and the third path to connect to the antenna wherein the amplifier receives a bypass signal originating from the transceiver, and wherein the bypass signal causes the Bluetooth signals and WLAN signals to pass through the amplifier without amplification when the second path is selected, but no gain is required.
