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.

Abstract: A diversity receiver capable of receiving a CDMA system (e.g., a W-CDMA system) and a TDMA system (e.g., a GSM system), with receive diversity for at least one system, is described. W-CDMA is often referred to as UMTS. In one design, the diversity receiver includes a first receiver for GSM and a second receiver for UMTS. The first receiver may be implemented with one receiver design, may be spec-compliant for GSM, and may also support UMTS. The second receiver may be implemented with another receiver design, may be spec-compliant for UMTS, and may also support GSM. The first receiver may include a lowpass filter having a bandwidth that is adjustable for GSM and UMTS. The second receiver may include a bandpass filter used to attenuate a transmit frequency range for UMTS. Each receiver may include circuit blocks that are used for both GSM and UMTS.
