When the element 3 functions as a linear amplifier, the input signal A passes through the combiner 7, as it is, so that the output of the element 3 is approximately proportional to its input. When the element 3 functions as a nonlinear amplifier, a harmonic generator circuit 6 generates odd-order harmonic components of the input signal A, and the combiner 7 combines them with the input signal A to form a rectangular wave signal B which is then fed to the active element 3.  <P>COPYRIGHT: (C)2004,JPO
