Hey 'nuts,
 
I'm looking for a good design for a 5 MHz frequency doubler.
 
The Wenzel Blue Tops HF doubler is said to be  based on a low phase
noise, public-domain NIST design:

The LNHD is a fixed-frequency HF doubler based on a public-domain design
developed by the National Institute of Standards and Technology (NIST
<http://www.boulder.nist.gov/timefreq/> ) for superlative phase noise
performance.

 
Can anyone point me at a this design?  I haven't had any luck finding it
on the web.
 
I'm open to suggestions on other doubler designs, as well.
