Have a look at,
< http://www.wenzel.com/pdffiles/diodedbl.pdf >
Also http://www.wenzel.com/documents/hints.htm indicates that the NIST
design uses JFET's but I can't find any more details.

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

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.
