Design Feature: Learn how to design evanescent-mode #waveguide filters - in a fraction of the time:

Filters are important components in many high-frequency systems, from commercial communications to electronic warfare (EW). A wide range of filters are useful at RF/microwave frequencies, including coaxial, cavity, stripline, microstrip, and waveguide configurations. While they tend to be large, waveguide filters offer high-quality-factor (high-Q) performance with low loss. Evanescent-mode waveguide filters can provide similar high-Q performance as propagating-mode waveguide filters, but in somewhat smaller structures. What follows is a method to design these filters without the need for time-consuming iterative methods.
