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:
<http://www.bluetops.com/Modules/lnhd.htm> http://www.bluetops.com/Modules/lnhd.htm 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. -ch _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
