Hi all, I'm looking to try my hand at layout for some microwave printed circuit boards. Would any of you know where I might find (on the internet) formulae for the design of various PCB pattern geometry for various microwave functions (ratrace mixers, wilkinson splitters, hairpin filters, duplexers, couplers, etc.)? If not, would anyone know a really good reference book with such formulae?
Jeff Condit P.S. I'm a degreed electrical engineer with 33 years experience, including a lot of PCB design for digital signals up to around 3.5 GHz and RF to around 70 GHz. However, I don't happen to currently have any good (read as very pricey) tools or references to help with calculating dimensions. I'd like to see how close I can get without 3D field solvers and do several iterations to get it right.
