IEEE APS/MTT Intuitive Microwave Filter Design with EM Simulation
April 10, 2018 @ 6:00 PM - 8:00 PM
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 10 percent or more. This is a “no math” approach to filter design that requires only simple algebra and no knowledge of complex filter synthesis techniques. The basic design method can also be expanded to include cross-coupled filters and multiplexers.
Two design flow examples have been prepared for this talk. The first is a high Q cavity combline bandpass filter and the second is a microstrip combline bandpass filter. We will determine which example to present by majority vote of the audience. Both examples will be available in the handout material.
