Abstract
A multiple power low power radio frequency amplifier. A first transistor amplifies a radio frequency signal at a substantially peak efficiency. The amplified signal is fed to a first impedance matching network. A second transistor receives the radio frequency signal and amplifies the signal at peak efficiency. The second transistor amplifier is connected to a second impedance matching network. A control circuit selectively applies a signal to be amplified to each of the transistors. One or more of the transistors may be enabled to amplify the radio frequency at the transistors peak operating efficiency independent of whether the other of the transistors is enabled to amplify the signal.
