Electronically Steered Arrays have become important components of many military and commercial systems. The ability to steer the null of the antenna as well as the main beam is important in the presence of jamming signals, or interference from other stations. This proposal presents a MMIC based solution for the beamforming weights of a 43.5-45.5 GHz system that is highly accurate, repeatable, and low cost in nature. Element to element phase tracking is expected to be less than three degrees, with RMS element to element tracking of 0.3 dB over the band. The chip will have low power consumption, and will allow for digital control
