摘要： An input signal is split into two signals, one of which is provided to a distortion generator and a the other of which is provided to a three-way combiner. The distortion generator comprises a single composite amplifier stage having two nonlinear amplifiers and two 180 degree splitters. The amplifiers produce signals having both odd and even-order distortion components because the amplifiers exhibit non-linear behavior. The distortion generator produces two output signals, one of which consists of the fundamental signal and odd-order distortion components, and the other of which consists only of even-order distortion components. The three-way combiner combines these two signals with a portion of input signal at a phasing that produces a resultant output having both the odd and even-order distortions suppressed. Equalizers may be used to provide phase and/or amplitude compensation for the two signals produced by the distortion generator before providing them to the three-way combiner.
