The use of a single source to drive a binary peak power multiplier

The binary power multiplier (BPM) recently proposed by Z.D. Farkas (ibid., vol.MTT-34, p.1036, 1986) requires a pair of radio frequency inputs whose phases are set independently. In this note, a method is presented in which a single source may be used to drive a BPM. Phase coding occurs at the course input, where the power is low and phase switching is straightforward. There is a loss in energy of about 25% but only a small reduction in peak power. >
