Abstract:
System and method for compensating for changes in an output impedance of a power amplifier uses an impedance compensating circuit with an impedance inverter coupled to the power amplifier. The impedance inverter of the impedance compensating circuit is configured such that an output impedance of the impedance inverter is proportional to the inverse of the output impedance of the power amplifier to compensate for changes in the output impedance of the power amplifier.
