摘要： Aspects of a method and system for a shared high-power transmit path for a multi-protocol transceiver are disclosed. Aspects of one method may include sharing a first power amplifier with a WLAN signal and a Bluetooth signal. The first power amplifier may amplify the WLAN signal and/or the Bluetooth signal simultaneously, or individually. A second power amplifier may be used to amplify the Bluetooth signal, where the first power amplifier may have a higher gain than the second power amplifier. Power may be reduced to the second power amplifier in instances where the first power amplifier is used to amplify the Bluetooth signal. The Bluetooth signal may be communicated to the first power amplifier via a switching circuit, which may comprise one or more switching stages.

摘要： An FM receiver including an FM antenna that receives continuous wavelength signals, where the FM receiver is coupled to the FM antenna and operable to alter a center frequency of a gain profile of the FM antenna. The FM receiver includes a low noise amplifier module that is coupled to amplify the continuous wavelength signal to produce an amplified RF signal therefrom. A down conversion module is coupled to mix the amplified RF signal with a local oscillation to produce an information signal. A filter module is coupled to filter the information signal to produce a filtered information signal. A demodulation module is coupled to capture audio information from the filtered information signal. A signal monitoring module is coupled to monitor the FM signal quality of a received continuous wavelength signal. The signal monitoring module produces a signal quality indication therefrom. An antenna control module produces a signal value based upon the signal quality indication, wherein the signal value operates to alter the center frequency of a gain profile of the FM antenna.
