RF and Optical Device Integration with Geoff Varrall

RF and Optical Device Integration There are some things that are obvious to say but are still worth saying and the same principle applies to technical writing; however much the reader knows and understands, every story has to have a starting point. That starting point is often some combination of material and manufacturing innovation that …

Set the Appropriate Measuring Range for Consistent Model Parameter Extraction with Gunter Kompa

Measuring the scattering parameters of a microwave transistor to develop an appropriate small-signal device model, the question may come up about the minimum frequency range needed to extract reliable  model parameter values. This issue has been studied intensively for microwave devices based on GaN technology and discussed in detail in my book Parameter Extraction and …

Getting Broad and Thorough Understanding in the Field of Device Modeling and Model Parameter Extraction with Gunter Kompa

My published book titled Parameter Extraction and Complex Nonlinear Transistor Models concerns with the following three key topics: Small-signal model parameter extraction Large-signal device modeling Large-signal measurement techniques In my first post, dated December 17, 2019, I explained the limitation of using the standard 15-element FET model for modern high power multifinger GaN devices. Similar …

About the Author with Tom Otoshi

Artech House supports its authors long after their books publish, and our authors continue to make huge strides in their fields. Today, we highlight author Tom Otoshi, whose book, Noise, Temperature Theory and Applications for Deep Space Communications Antenna Systems, continues to be relevant today: In 1961, Mr. Otoshi joined the Jet Propulsion Laboratory (JPL) at …

Diffraction Modeling and Simulation with Gökhan Apaydin and Levent Sevgi

When Artech House authors write their books, we ask them what they want their readers to get out of the project. In this series, we show you what our authors, in their own words, wish to impart upon readers. Gökhan Apaydin and Levent Sevgi, authors of Electromagnetic Diffraction Modeling and Simulation with MATLAB, describe what their …
