Abstract
An amplitude control circuit and variable phase shifter driver, employable in electronically steerable antennas, compares amplitude and phase command signals for the amplitude controller and phase shifter with command signals derived from the amplitude ratio and phase difference between a reference r.f. signal and an r.f. signal at a selected location. The difference signals resulting from this comparison are added to the amplitude and phase shift command signals and applied to the amplitude controller phase shifter drivers to adjust the amplitude controller and phase shifter.
