Abstract

In four-frequency converters and amplifiers, the four main frequencies f p , f e , f(+) and f(−) are used. Devices of this type are little used in practice, because of the difficulty in producing them satisfactorily. The only one which is of interest, and of which some practical examples have been mentioned in technical literature, is the sum-frequency converter [1]. The representation of four-frequency circuits by equations is much more complicated than for three-frequency circuits. It is for this reason that we have studied the two families of circuits independently, instead of considering the second as special cases derived from the first by suppression of f(+) or f(−).
