APG-81 TR module?

[viperzerof-2]

I was doing so research and I found this Patent for a TR module design assigned to Northrop Grumman. I noticed it looked just like the APG-81 module.

Looks fairly accurate I'd say, good find!

Really interesting find and I agree that this patent and that picture match very well and the patent describes highly advanced T/R module for the time. And the time this patent was filed definitely also matches the development of AN/APG-81 and thus also the T/R module. There is also clear goal of lowering costs which aligns well.
