Abstract:
Power amplifier having a common input and a plurality of outputs. In some embodiments, a power amplifier can include a plurality of signal paths having a common input node. Each signal path can include a dedicated amplifier stage, and be configured to be capable of amplifying a radio-frequency (RF) signal received at the common input node. The power amplifier can further include a bias selector configured to provide a bias signal to the dedicated amplifier stage of a selected one of the plurality of signal paths to thereby allow amplification of the RF signal through the selected signal path. Such a power amplifier can be implemented in products such as a die, a module, and a wireless device.
