Hey, you have forgotten mine :-)

The phase noise plot includes the GPS receiver/ MTI-260 and the doubler.
Thanks! added link to the ohwr page
It's a shame if the transistors aren't available anymore - for as-low-as-possible phase noise I guess one can achieve better performance with a discrete design compared to op-amps.
I've looked inside some commercial boxes where they pair two LMH6702s together to get a 3dB reduction.. (a bit like the ADA4898 LNA idea!)
