IEEE AP/MTT Atlanta Chapter Presents: Vacuum Electronics to Power MMW Applications

Share

The benefits of operating in the millimeter wave or extremely high frequency (EHF) region of the electromagnetic spectrum (spanning from 30 to 300 GHz) are well known to the RF electronics system designer. Of course the challenges of working in this spectral region are also well documented, including high signal attenuation, tight antenna pointing accuracy, and general lack of system components, especially RF sources.

Device development over the last decade has served to significantly increase the transmitter designer’s toolbox for mm-wave RF power sources. As will be described, compact, efficient mm-wave vacuum electronics devices and integrated power amplifiers have been developed over essentially the entire EHF band. Examples of development at L3 will be discussed along with a discussion of applications.

Biography:

Dr. Carter M. Armstrong

VP, Research and Development, L3 Technologies Electron Devices

Dr. Carter M. Armstrong is the Vice President of Research and Development at the Electron Devices Division of L3 Technologies in Torrance, CA. Previously, Dr. Armstrong served as the Vice President of Engineering at the L3 Electron Devices division in San Carlos, CA (former Litton Electron Devices). In 2017, the L3 San Carlos microwave tube facility was closed and consolidated with the L3 facility in Torrance (former Hughes/Boeing EDD). Before joining L3, Dr. Armstrong worked at Northrop Grumman, the Naval Research Laboratory and North Carolina State University. Dr. Armstrong served on the DoD’s Advisory Group on Electron Devices from 2004 to 2009 where he co-chaired a review on compact THz sources. A summary of the findings of the review was published in the September 2012 issue of IEEE Spectrum entitled, The Truth about Terahertz. Carter published another article in Spectrum 2015 entitled, The Quest for the Ultimate Vacuum Tube. Carter received his undergraduate degree in physics from Rutgers University and his PhD in plasma physics from the University of Maryland at College Park. Dr. Armstrong has been an adjunct professor in the Electrical and Computer Engineering Department at the University of Wisconsin – Madison since 1996. On May 21, 2013, Dr. Armstrong received the IEEE John R. Pierce Award for Excellence in Vacuum Electronics at the 14th International Vacuum Electronics Conference in Paris, France. Dr. Armstrong is a Fellow of the IEEE.
