Webcast: Small Antennas

Thursday, March 31st, 2011

Besser Associates webcast series with Microwave Journal continues in April with a presentation on Small Antennas this April 19th at 8AM Pacific/11AM Eastern/3PM UTC. The session is recorded, so even if you cannot attend the live event, you can still view the talk.

Antenna miniaturization has been the subject of intense investigation over the past decade with the significant commercial growth of wireless devices. This presentation provides an overview of the basic theory and concepts associated with electrically small antennas.

Outline:
• Small Antennas Introduction
• Performance Limitations (impedance, radiation patterns, bandwidth, efficiency, and quality factor)
• Design Techniques (dielectric loading, impedance loading, linear loading, top-loading, folded configurations)
• Recent Advances

Visit Besser Associates at IMS2011 in Baltimore

Thursday, March 31st, 2011

Visit Besser Associates at the upcoming IMS2011 Symposion/Exhibition in Baltimore this June 7-9. We will be on the show floor in Booth #1707. From the IMS website:

“The 2011 IEEE MTT-S International Microwave Symposium is the world’s premier microwave conference. It features a large trade show, technical sessions, workshops and panel sessions in covering a wide range of topics. Attendees are interested in wireless communication, radar, RF technologies, high frequency semiconductors, electromagnetics, commercial and military RF, microwave and mm-wave electronics and applications. Attendees represent an international group of engineers and researchers developing technologies to support the microwave and RF industry.”

We hope to see you there!

Learn RF Fundamentals Live via Web Conferencing

Tuesday, March 29th, 2011

In today’s environment of limited budgets for travel, our web classroom courses are more popular than ever. Enjoy the benefits of a live, interactive course without leaving your workplace!

This course provides circuit-level designers with the essential concepts needed to work effectively with high frequency electronics. Participants gain analytical, graphical, and computer-aided techniques to analyze and optimize RF circuits in practical situations. The course addresses linear active circuit design, focusing on stability, bandwidth, and noise considerations.

Learning Objectives:

Upon completing the course, the participant will be able to:

• Describe RF circuit parameters and terminology.

• State the effects of parasitics on circuit performance at RF.

• Use graphical design techniques and the Smith Chart.

• Match impedances and perform transformations.

• Predict RF circuit stability and stabilize circuits.

• Design small signal and low noise RF amplifiers.

Target Audience:

Professionals required to work in high frequency domains for the first time, as well as seasoned veterans, will benefit from this comprehensive overview of practical design techniques. An electrical engineering background (or equivalent practical experience) is recommended, as well as a familiarity with complex numbers.

Schedule
Monday, June 13 9:00 – 10:30 AM Pacific Time
Tuesday, June 14 9:00 – 10:30 AM Pacific Time
Wednesday, June 15 9:00 – 10:30 AM Pacific Time
Thursday , June 16 9:00 – 10:30 AM Pacific Time
Friday, June 17 9:00 – 10:30 AM Pacific Time

The course is taught on-line using our Web classroom format: simply log-in to the 90 minute live conference each dayright from your workplace. The instructor’s audio and presentation are delivered over the computer screen and speakers. Students can ask questions at any time via the chat window – or between sessions via email.

Webcast: Oscillators

Friday, March 4th, 2011

Besser Associates in cooperation with Microwave Journal will present a one hour webcast on Oscillators this Tuesday, March 15, 2011 8:00 am Pacific Daylight Time (San Francisco, GMT-07:00). The oscillator, a key component in wireless products, has a major impact on system performance. Today’s designs must meet demanding stability and phase noise requirements. This presentation provides an overview of oscillator design, specifications, and the topologies used to meet these performance challenges. Besser Associates instructor and IEEE Life Fellow Allen Podell will give the presentation and answer selected questions in a 10-15 minute Q&A session.

Outline:
-Introduction
-Specifications
-Types/Topologies
-Variable Frequency: VCOs
-Design Overview
