Webcast: Mixers & Frequency Conversion

Friday, April 29th, 2011

The Besser Associates/Microwave Journal webinar series continues with a presentation on Mixers and Frequency Conversion this May 17 at 8:00AM Pacific Time. Frequency conversion is a critical function in all wireless systems. A key component used to accomplish this is the mixer. Designers need to understand different mixer topologies and specifications in order to meet their system requirements. This webinar provides a brief overview of frequency conversion and introduces the mixer as the component used to accomplish this function.

• Why Convert?
• RF System Architectures
• How many conversions?
• How to Convert? What is a mixer figure of merit?
• Passive diode mixers versus passive FET mixers
• Monolithic silicon active mixer issues
• Comparing Mixer Specifications
• Design Overview
This talk will be presented by Allen Podell:

Allen Podell, an IEEE Life Fellow, has designed monolithic and discrete circuits on gallium arsenide, silicon, sapphire, and plastic. With a solid foundation in device-circuit interaction, he specializes in the practical realization of modern circuit techniques. An author of over 70 technical papers, Mr. Podell founded three companies (Anzac Electronics, Podell Associates, and Pacific Monolithics) and he holds 60 US patents ranging from IMPATT diodes, silicon power transistors, and 3-decade bandwidth microwave components, stereo demodulators, antennas, gallium arsenide integrated circuits – and more recently, high power, wideband components. Previously, as VP of Technology at Besser Associates and later at Podell Consulting, Mr. Podell has taught advanced wireless design courses and provided consulting services worldwide.

“No-travel” Options for Instructor-Led Training

Friday, April 29th, 2011

Do you need RF/Wireless training, but don’t have the time or the budget to travel to one of our public courses? Besser Associates has options that can help you get the training you need without traveling. One option is simply to bring our training to your site. If you have a group that needs training it makes more sense for our instructor to come to you than to have your group fly to our training location. On-site training usually works best for groups of six to eight people or more, depending on where you are located (Besser Associates offers on-site training internationally as well). Simply contact the office for a no-obligation quote.

Another option is  to use web-conferencing as the meeting place for the students and instructor. We use the term “web-classroom” to describe this environment because we like to promote as much interaction with the instructor as possible. Similar to our regular classroom courses, the class size averages about 15 participants, so that there are plenty of opportunities to ask questions. Students can also ask questions via email between sessions, and the instructor usually chooses to give the answer in the next session, so that all participants can benefit. We currently have three upcoming courses scheduled with this format, and corporate-exclusive sessions can also be scheduled for your individual group to meet your timing needs.

Besser Associates Instructors at the IMS/MTT June 2011

Friday, April 29th, 2011

Several Besser Associates instructors are actively involved in the upcoming International Microwave Symposium this June in Baltimore.  Their activities are briefly summarized below. If you would like more detailed information, the best place to get it would be from the show program, which is available as a PDF file.

Steve Cripps will be receiving the distinction of IEEE fellow for his contributions to broadband and high-efficiency RF power amplifiers. Dr. Cripps is also participating in several tecnhincal sessions on RF PA design, linearity, behavioral modeling and baluns. Be sure to review the outline for his upcoming course with John Wood on PA linearization in Boston.

John Wood will be contributing to workshops on RF power amplifier linearization and modeling, as well as serving as chairman for a technical session on GaN power amplifiers. In addition, he has contributed a paper on transistor modeling and served on the technical paper review committee.

Richard Ranson is one of the organizers of a workshop on practical approaches to software defined radio. He is also presenting an upcoming course on system design in Boston.

Earl McCune will be participating in a workshop on reconfigurable, multi-standard low power applications of wireless technology. Dr. McCune will also present a course on digital signal formats for Besser Associates this summer, featuring his recenly published book on the same topic.

Ali Darwish is co-chair for a technical session on GaN and LDMOS linear power amplifiers, in which is is also presenting one of the papers. He is co-chair and one of the presenters for a focus session on microwave engineering around the world. He serves on the technical paper review committee, as well as acting as a regional coordinator. Dr. Darwish has two upcoming courses this year with Besser Associates. He will present a course on MMIC design this summer in San Jose and another course on RF power amplifier design in Dallas this November.

Waleed Khalil is the chair of a technical session on wide tuning range oscillators as well as acting on the technical program committee. We are offering his course on phase noise and jitter via two three-hour sessions in the web classroom environment this October. He will also present a course on RF CMOS design this fall in Dallas.

Ed Niehenke is one of the organizers for workshops on medical and biological sensors and systems and GaN MMIC design. He is a co-chair for a technical session on advances in mmwave and THz technologies. He has acted as a consultant to the technical program and steering committees as well as serving on the technical paper review committee. His updated course on transceiver architecture design will be added to the schedule of course offerings this December in San Jose.

We hope you get a chance to make it to the show. Besser Associates will be on the exhibition floor at booth number 1707. See you there!
