摘要：
A transmit amplifier stage operable to amplify a transmit signal comprises power amplifiers and switches. The power amplifiers include at least one fractional power amplifier operable to provide fractional power to amplify the transmit signal, where the fractional power is a fraction of the full power. A switch has a plurality of positions, where a position directs the transmit signal to a selected power amplifier.
