Summary

The successful design of mm-Wave (Millimeter Wave) monolithic microwave integrated circuits (MMICs) and RFICs is the result of a disciplined design approach. This course covers, in detail, the theory, and practical strategies required to achieve first-pass design success. Specifically, the course covers the implementation of mm-Wave circuits on SiGe, GaAs, InP, and GaN substrates including instruction on processing, masks, simulation, layout, design rule checking, packaging, and testing. Numerous design examples are presented with emphasis on increasing yield, and reliability.
