1. A method of detecting the output power of a power amplifier comprising the steps of:

  • sensing the magnitude of the voltage at the output of the power amplifier;

    sensing the magnitude of the current at the output of the power amplifier; and

    generating a signal using a summing element to combine a signal relating to the sensed voltage with a signal relating to the second current, wherein the generated signal is proportional to the output power of the power amplifier.
