Patent abstract
An apparatus and method for adapting a power amplifier to a variable load includes comparing the actual output power to the expected output power, modifying a drive signal to the power amplifier, measuring the value of at least one electrical parameter, determining the difference between the measured value and a predetermined value, and periodically adjusting the drive signal according to the difference. The parameters modified include, but are not limited to, the power delivered to the input of the power amplifier, the DC power supply voltage to any stage of the power amplifier, and the current setting bias values.
