Hi Rick.

There was an article quite some time ago which listed a computer program
for calculating a diplexer of the same type as you show on your website.
Speaking of which, I like how you presented the information about diplexers.
Well done, and easy to understand.

I am not sure if you will be able to get a copy of this article, but it
was from:

'PROGRAM BY JEAN-LUC DUGAS
'NOVEMBER 1986 R.F. DESIGN PAGE 97

The program allows choosing Highpass/Lowpass or Bandpass/Bandstop.

According to the RFdesign website, they plan to eventually have archived
online back issues, but so far they only go back to 1999.

Anyway, here is the archive website:
