And thank you very much for fixing the insert tool! Just pulled and
compiled, it works fine.

I shall try when I hit it again. I have also a polygon dicer (at least I believe
it is) problem somewhere which I want to submit when I have more details.

Switching of microwave signals. Actually there are two different circuits,
one based on RFMD's RFSW2041D and another one based on Hittite's HMC975.
Both circuits have a square shape whose side is 8.89mm (350 mil).
Actually the design of the (milled aluminum) enclosure is (at least for me)
much more difficult than the PCB, in which everything is at an unusual
scale, but otherwise very simple (the most complex of the 2 circuits
has less than 10 components).

Gabriel
