Tavarnelle said:Excuse me, webdog,
I know that eagleware permits sintesys and simulation of microstrip (on substrate) and not on AIR... Is it right?
I'd like to design filters on air, for example using a wave guide with iris and / or screws
Btw, I am interested on your software, if it design such filters :wink:
Thank you very much!!
Tavarnelle.
it seems these programs have bugs and aren't updated since 2000.nandopg said:I've been using Parfil and Elliptic from WaveCon (http://www.waveconsoft.com/) very successfully up to 12GHz.

very valuable revision !nandopg said:Again, I reinforce that if somebody needs a good program to design COAX microwave filters Parfil and Elliptic are the right choice.
but our object is not quite coax.Tavarnelle said:I'd like to design filters on air, for example using a wave guide with iris and / or screws.
very strange declaration from person who uses programs five years and seems did not try to use them for microstrip filters!nandopg said:Also I would like to ask to those members without the required experience to help others to be quiet.
i need not coax filters! look please in the first and third posts of this thread. both post's author is Tavarnelle. do you see word "coax"? i can see words "cavity", "waveguide" and "irises". yes, i can see word "interdigital" too. due to this word you have right tell us your opinions. but you have no right to shut up other people, having greater experience in filter design. look at following inequality:nandopg said:My dear u_f_o,
If you need coax filters build up on cavities, as it is the case in the first post of this thread, you have to use Parfil or Elliptic. No doubts.
