First Claim
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 dedicated to transmissions of the WLAN signals;
a second path coupled between the antenna and the transceiver dedicated to simultaneous receptions of the Bluetooth signals and the WLAN signals; and
a third path coupled between the antenna and the transceiver dedicated to;
transmissions only of the Bluetooth signals when a WLAN link is active;
andtransmissions and receptions of the Bluetooth signals when the WLAN link is active and in a power save state, and when the WLAN link is inactive.

Abstract
A radio frequency (RF) front-end configured to share transmissions and receptions of Bluetooth signals and WLAN signals. In an exemplary embodiment, the RF front-end comprises a first path coupled between an antenna and a transceiver dedicated to transmissions of the WLAN signals; a second path coupled between the antenna and the transceiver dedicated to simultaneous receptions of the Bluetooth signals and the WLAN signals; and a third path coupled between the antenna and the transceiver. The third path may be dedicated to transmissions only of the Bluetooth signals when a WLAN link is active; and transmissions and receptions of the Bluetooth signals when the WLAN link is active and in a power save state, and when the WLAN link is inactive.
