Abstract
Power amplifier systems with non-linear antenna impedance for load compensation are provided. In certain embodiments, a method of power amplification in a mobile device is provided. The method includes generating a radio frequency input signal using a transceiver, amplifying the radio frequency input signal to generate a radio frequency output signal using a power amplifier, and transmitting the radio frequency output signal using an antenna, including compensating the power amplifier for a change in output load in response to a change in signal power using a non-linear impedance versus output power characteristic of the antenna.
