First Mixer (UHF) in CRFU_2a

First mixer is a double balanced Gilbert cell with a common base input stage. This mixer
is optimized for being driven single ended. The performance of the mixer depends highly
on the application and the mixer is therefore simulated with the "real" circuit around it.
The spread on the external components is included.
