interim layout

I like to do the tricky parts of a pcb layout myself, rather than
trying to explain it to a pcb designer. Actually, I don't know how
parts should be arranged until I push things around for a while. It's
chaos until something clicks.

That has two 20 GHz $20 MMICS summing into a 20 GHz $350 distributed
amplifier. That's scary. This will be a proto board, one corner of the
eventual board in the product.

I like reference designators that I can see without a microscope.
These are 60 mils high and they sure get in the way.

I guess I should rotate J10 and tuck it in closer to U14. That trace
looks kinda like an antenna. I'd have to put a goofy notch in the real
board for connector access.
