Abstract
A system for detecting the envelope of a signal is provided. The system includes a first envelope detector generating a first envelope signal of an input RF signal, such as an envelope signal representing the positive peak envelope of the input RF signal. A second envelope detector generates a second envelope signal of the input RF signal, such as an envelope signal representing the negative peak envelope of the input RF signal. A signal combiner receives the first envelope signal and the second envelope signal and generates an even-order harmonic compensated envelope signal, such as by compensating for the difference between the positive peak envelope and the negative peak envelope.
