Cross-coupled filter synthesis software CoupleFil - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. 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.
