Upcoming Open Enrollment Training Classes

June 1 - 5, 2020   These courses will be taught online. ​Continuing Education Institute    www.cei.se

​​#31  High Q Cavity Filters and Multiplexers​​
Chebyshev and cross-coupled cavity combline filters are the preferred technology when high performance and relatively low cost filtering is required. Learn EM simulation and unique optimization methods that are keys to rapid, successful design. (3 day class)
https://www.cei.se/course-031-high-q-cavity-filters-and-multiplexers-group.html

 #30  PCB Filters and Multiplexers Using Standard SMT Components
Design inexpensive, custom filters for your system that are directly integrated into the PCB environment. Discover the most useful topologies as well as techniques to overcome a limited standard parts library. (2 day class)

​​Intuitive Microwave Filter Design With EM Simulation​​
      
   Microwave filters are one of the basic building blocks in RF systems along with amplifiers, mixers and oscillators. At some point, you may be called on to design or specify a filter, even though you are not a filter design expert. Luckily, there is simple design method for narrow band filters that is easy to learn and quite universal. It can be applied to any lumped element or distributed topology and any manufacturing technology except SAW/BAW. And, the method is valid for bandwidths from a fraction of a percent up to 20 percent or more.
   This technical lecture is a “no math” approach to filter design that requires only simple algebra and no knowledge of complex filter synthesis techniques. The root of the design flow is based on Dishal’s method with the addition of EM simulation for accuracy and port tuning for updates to the filter geometry. The basic design method can also be expanded to include cross-coupled filters and multiplexers.
    Two design flow examples have been prepared for this technical lecture. The first is a high Q cavity combline bandpass filter and the second is a microstrip combline bandpass filter. The design flow can be realized using software from many different vendors. Example project files will be made available to attendees.
