challenge might be test equipment when you're debugging your 40 GHz
synthesis chain.

There's a fair amount of test equipment around to 40.0 GHz, but it is not
cheap even on the used market. But above 40.0 GHz it gets even more
expensive, as a lot of kit stops there. So a spectrum analyzer that works
to 40.1 GHz is going to cost serious money.

I don't know what ones chances of feeding 10.04 MHz into the 10 MHz
reference input to 40 GHz test equipment to make it work to
40*10.04/10=40.16 GHz. I suspect that you could get away with it.
