Evanescent Filters

David Jones <david.g6feo@...>

I am looking to make an evanescent filter for 5.7GHz.

I've looked on the web and found a lot of information, but...

Is there an idiots guide to designing evanescent filters or a program
that will do all the hard work?

What I'm looking for is how to calculate the distances between the feed
points and tuning screws for different waveguide or pipe sizes.

73, David.
