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.

NOW AVAILABLE ON-DEMAND. This course is broken into 9 recorded live online sessions with each session lasting approximately 2.5 hours. The course was originally spread out in three parts over a three month period. Each part contains 3 sessions. Each session was recorded to support students that want to review the live events or for those that cannot attend the live events. With your enrollment in each course, you will be able to view recordings of the live sessions on-demand throughout the 30-day program access period.

The past schedule for 2025 was as follows:

Part One: June 10, 11, 12 - These 3 sessions are available on-demand.

Part Two: July 22, 23, 24 - These 3 sessions are available on-demand.

Part Three: September 2, 3, 4 - These 3 sessions are available on-demand.

Learning objectives

Upon completing the course you will be able to:

Learn the advantages and limitations of MMIC Designs
Take advantage of the inherent benefits of MMICs over hybrid circuits.
Account for the parasitics of the active device.
Design biasing networks for active circuits.

The class flow from semiconductor materials to devices to circuits was excellently done. This was also the best unified treatment of passives and actives that I have personally seen - I learned a lot, thank you! K.E.

Excellend job on the pacing and adjusting to the varied student levels! It's a rare pleasure to take a class that is instructed with the same high quality and organization as the information contained in it. I greatly appreciated the supplementary comments and slides, in addition to the paper references in the printed material. I will be recommending this course to my colleagues for the clarity of instruction and the wide range of information covered. K.E.

Mr. Darwish is very experienced in PA design and able to answer some of the questions that have troubled me for a long time. Y.C.

There was great explanation of materials and very good refreshment of the previous subjects. Ali explained the subjects very smoothly - great instructor. F.T.

- willing to share his knowledge - the way he tried to teach: deriving the things if he needs to make things easy - the way he acts in teaching encourages you Thank you! O.C.

The instructor has excellent teaching skills. He can teach ver complex structures in an easy way. He is also helpful for any kind of problems and questions related with the course and industry. S.O.
