Abstract: An RF system comprising of outputs to an electronically scanning antenna for radiating electromagnetic energy; at least one waveform generator; two multiphase phase-locked loops integrated with the waveform generator, the phase locked loops operating to provide multiple shifted phases to a waveform. Optionally, the two multiphase phase-locked loops may each be divided down by a bank of frequency dividers to further increase the number of phase shifts. The phases generated from each multiphase phase-locked loops are selected with multiplexers then mixed together. These upper or lower sidebands are then mixed with the up converted waveform which results in a phase shift for the waveform associated with each antenna element.
