Cross-coupled filter synthesis software CoupleFil - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi filter designers!

For narrow single or multiple bandpass filters it is advantageous using cross-coupled filter designs. Since cross-couplings cause total absorbability for desired frequencies, a cross-coupled cavity filter needs fewer resonators than a simple-coupled one, what will result in a better through loss.
CoupleFil reduces the time and effort to reach optimal solution for cross-coupled filters.
