Patent attributes
Radio-frequency amplification systems, devices and methods. In some embodiments, an amplification system can include a supply circuit configured to provide a high supply voltage in an average power tracking mode. The amplification system can further include an amplifier configured to operate with the high supply voltage and provide an impedance that substantially matches an impedance of a component coupled to an output of the amplifier. The amplification system can further include a signal path configured to route an amplified signal from the output of the amplifier to the component, with the output path being substantially free of an output matching network.
