Abstract
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.
