Abstract
The present invention is a method and apparatus for providing an output signal having a high average power and the method has the steps of providing a standard frequency; forming a plurality of input signals from the standard signal such that each of the input signals has a predetermined frequency which is different from the frequencies of the other input signals; phase shifting at least one of the input signals such that at least one of the input signals has a phase different from the phase of the other input signals; combining all of the input signals to produce a combined signal; and amplifying the combined signal to produce the output signal. In one embodiment all of the input signals are phase shifted relative to one another and in another embodiment all of the input signals are equally phase shifted relative to one another except for one which is of opposite phase. Also all of the input signals are equally spaced in frequency relative to one another or have a common divisor in spacing. The apparatus implements the method of the present invention.
