The IEEE Foothill Section invites you to a Presentation on
An Introduction to Software Defined Radio for Microwave Engineers
Without a doubt, you have heard of Software Defined Radio (SDR). As the Wireless Innovation Forum defines SDR, in the simplest wording possible, this is a radio system, which transmits and receives electromagnetic energy, with some functions in the physical layer generated and controlled by software. So, we expect that there will be some hardware components involved. On the transmit side, this would mean antenna, power amplifier, digital-to-analog convertor; on the receive side, antenna, low-noise amplifier, analog-to-digital convertor. This leaves a large engineering problem to specify, design, and develop the software that will make the SDR system actually function as an integrated system. This subject should be of immediate interest to all our IEEE Foothill engineers interested in RF, Microwaves, communications systems, and of course, software engineers.
Today, the IEEE Foothill Section will sponsor a technical presentation with a summary, demonstration, and prognosis of the state-of-the-art in SDR. We will welcome our guest speaker, Dr Jeffrey Pawlan, IEEE Microwave Theory and Techniques Society Distinguished Lecturer, to fill us in on the status of current IEEE topic.
Saturday October 5, 2013, starting at 9:30 AM with Continental Breakfast, Presentation at 10:00 AM; concluding at 12:00PM
DeVry University, Pomona Campus, 901 Corporate Center Drive, Pomona CA , Room 204

Summary of Presentation by Dr Jeffrey Pawlan:
This lecture will begin with the definition, history and evolution of Software Defined Radio (SDR). RF/microwave engineers will find it clear and understandable because analogies will be made to conventional classic radio systems and components. The lecture will then introduce the concepts of oversampling and undersampling as it applies to SDR. There will be an introduction to the details of correctly driving and implementing an A/D converter as this is one of the important areas that the RF/microwave engineer will be asked to do. There will be an introduction and explanation of the firmware and software portions of SDR and a comparison with state-of-the art conventional analog circuitry will be shown. A live demonstration of SDR will be presented.
This lecture will be of strong interest to MTT members as demonstrated in the many workshops and lectures that Jeffrey Pawlan has already been asked to give. Software Defined Radio (SDR) is the culmination of advances on several fronts and probably the most significant area of development in radio systems today. The entire worldwide cellular system uses SDR. NASA and the US military communications are now almost exclusively using SDR. Soon new automobile radios will be SDR to accommodate multiple modulation formats. The role of the RF/microwave engineer in this new technology will be shown so that the audience can adapt and feel that their skills are needed in the evolving field of radio communications
Speaker’s Biography
Jeffrey Pawlan (M 1989, SM 1996) has been a consultant as owner of Pawlan Communications for 25 years. Prior to that, he had worked for many companies in California in very diverse areas of analog, RF, and microwave design and has been an engineer for 40 years. Some of his work was for NASA projects including the very successful design of the SARSAT/COSPAS search and rescue satellite ground stations. He also taught engineering part-time. Born and raised in the Los Angeles area, he attended UCLA and several other universities. He enjoyed learning many different fields and has 13 years of higher education including a Doctorate degree.
He has worked on projects for consumer, industrial, and military applications covering a wide range of the spectrum from LF to 50GHz. In addition to his primary involvement with the MTT society, he is also a member of the UFFC (frequency control) concentrating on low phase noise oscillators and phase noise measurements, a member of the AP-S, and also the Communications Society. He has published several papers and has two patents. He is serving as a member on the IEEE SCV Section ExCom and also is on the ExCom of the Central Area, Region 6. He is a member of two MTT technical committees, MTT-9 and MTT-20.
He has been designing RF and microwave hardware for Software Defined Radio uses within instrumentation and military satellite communications since 1984. For the past nine years he has been concentrating on Software Defined Radio technology with his own radio designs including the development of very capable software and hardware. He has presented talks in a workshop at the 2010 IMS in Anaheim, the 2011 IMS in Baltimore, the 2012 IMS in Montreal, and also at chapter meetings and a short course.
He was a guest lecturer at the Czech Technical University of Prague in 2010. In 2011 he was a guest lecturer at the University of Aveiro Institute of Telecommunications in Portugal where he presented a one week course on RF design and SDR. In 2012 he was a guest lecturer at the Czech Technical University in Brno. He presented a half-day tutorial on SDR at the WAMICON conference in April 2012.
