Vector Network Analysis by Saied Seghatolesalami
We will be covering a few or all of these items:
- Locate points on the Smith Chart based on the impedance and admittance of a load
- Learn how to place reactive components in series and in parallel using a Smith Chart
- Design a matching network between an antenna and a transmitter
- Calculate admittance from impedance and vice versa using a Smith Chart
- Calculate the impact of placing a length of transmission line cable between the load and the transmitter
To accomplish this, we must learn how the Smith Chart is constructed. For that, we need to review some basic electrical parameters such as voltage, current, phase, reflection coefficient, SWR, resistance, reactance, conductance and susceptance. Depending on the audience, we can make the content more or less mathematical.
Saied Seghatoleslami is in his second retirement. He is vice president and treasurer of Rensselaer Alumni Association and president of the Delaware Valley Radio Association (W2ZQ). He spends his spare time cooking, building a 500 watts antenna tuner, refining his ham radio logger and contesting software and participating in ham radio CW contests. He is also an industry advisor to the RPI Electrical and Computer Systems Engineering department students.
After his first retirement in 2013, he was the executive chairman of C360 Technologies, a sports tech startup, president of Pypestream, a conversational AI startup, and the principal in multiple acquisition and business turn around projects in the technology sector for private equity funds.
Saied joined Bell Labs in 1982. His career in Bell Labs and successor companies (Lucent, Avaya) over the succeeding 31 years, spanned design engineering, engineering management, and corporate executive roles. His executive responsibilities included business unit general manager, vice president of business operations, vice president of quality assurance, and vice president of product management. As an engineer at Bell Labs, he designed integrated circuits, analog circuits, and performed systems analysis.
After graduating from RPI, he joined Bendix Corporation as a test engineer on the Space Shuttle program. While working at Bendix, he was recruited to join a startup, Vydec, building word processing machines.
Saied received his bachelor’s and master’s degrees in electrical engineering from Rensselaer Polytechnic Institute in 1974 and 1975 and completed the Harvard Business School Advanced Management Program.
