    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： Aspects of a method and system for sharing low noise amplifier (LNA) circuitry in a single chip Bluetooth and wireless local area network (WLAN) system are disclosed. Aspects of the system may comprise a chip with integrated WLAN and Bluetooth radios. RF signals may be received via a single antenna coupled to a shared LNA integrated in chip. When WLAN signals are received they are communicated from the shared LNA to a subsequent amplification stage integrated within the WLAN radio. When Bluetooth signals are received they are communicated from the shared LNA to a subsequent amplification stage that comprises a transconductance amplifier integrated within the WLAN radio and an LNA load integrated within the Bluetooth radio. Gains in the LNAs, the transconductance amplifier, and/or the subsequent WLAN amplification stage may be dynamically adjusted. Outputs from the subsequent amplification stages may be communicated to mixers for further processing.

    摘要： An NFC-enabled device includes a load modulation communication section providing two or more selectable changes in the load impedance across the antenna terminals. At least one of the two or more selectable changes is dependent on both the transmit data and the concurrently detected strength of a tag reader field coupled to the NFC antenna.
