Amateur Radio Site Of  VE1XYL & VE1ALQ, or VE9DW  

This is a Schematic for a very simple Weak Signal source that I used for years. It work FB up to
and including 10.368Ghz (432nd harmonic). Have not tried 24Ghz ( ;o}

I recommend  5VDC full size Computer TTL Osc rather than the CMOS versions that are now available.  The TTL version produces stronger harmonics than the CMOS version.

Using a precision attenuator on the output it can be used connected directly to the DUT (device under test).
