tremendous array gain, noise improvement, and beamforming capabilities for a variety of applications such as radar and communications. Such phased-array systems have traditionally been implemented using compound semiconductors in a module-based approach. However, the dominant cost of these systems is in the electronics. Thus, the large number of active elements involved results in a very high price tag limiting the size of the phase arrays. Integrated CMOS solutions offer an opportunity for dramatic cost and size reduction in such systems. The high yield and repeatability of silicon ICs allows the entire transceiver to be integrated on a single chip resulting in an order of magnitude reduction in the overall system cost [1, 2]. Silicon CMOS also offers new opportunities for concurrent programmable multi-beam multi-band solutions over
