I think I may have finally finished the Version 2 Schematic of my "Ridiculously Over Engineered SWR meter" or ROES for short.
Its basically an Arduino based SWR meter with an LCD display (not depicted here as that is a seperate shield). But it provides all the functions of a Vector Network Analyzer (VNA) and goes way beyond your typical SWR meter. The only thing it doesn't have that a VNA would have is a function generator, as it relies on the transmitter to do that.
Generally you'd hook a directional coupler into your feedline (I'll be providing that as a seperate kit) and then tie the forward and reflected ports into this shield.

@freemo I used the AD8302 recently as part of an analogue phase detection system for a linear accelerator. I hadn't thought about how they could be used in a VNA.
@comphys yea though you do need two as you can see. It really annoys me how they are limited to 180 degrees
Any criticism on my circuit, I really need some eyes on it
@freemo I don't understand this, but it looks very cool! Makes me want to add electrical engineering to my already huge pile of things to learn lol
