摘要：
Embodiments of a two-stage bypass power amplifier are provided. In general, the two-stage bypass power amplifier is configured to receive a RF signal that is to be transmitted to a remote device and provide gain to the RF signal prior to the RF signal being transmitted to the remote device. The two-stage bypass power amplifier is configured to operate efficiently (in terms of power) at two different gain or output power levels and can be extended to operate efficiently at additional gain or output power levels.
