How do i reduce the drivelevel of the crystal to 100 uW?

<< < (5/5)

Thats a lot of current :D !

Well, the single tube crystal controlled power oscillators were called "rock crushers" for a reason.
A style not really compatible with small modern crystals.

The 'Xtal Current' meters on Radar receivers was a measure of local oscillator injection into the mixer and crystal health 1N21 for the 1-2GHz stuff and 1N23E(R) for Xband. Times have changed.

And in hobbyist use 1N21 works also for X-band (and C-band).  ;D
