>How difficult is it to multiply a frequency standard from 10MHz to 100MHz? WA1ZMS has successfully done the kind of thing you want to do. He used a clean 5 MHz OCXO as a source to generate milimeter wave LO's. See the doubler and direct synthesizers shown here: http://www.mgef.org/zms_134_VUCC.htm and http://www.mgef.org/zms_241_vucc.htm In addition to a doubler, one of those schemes uses x9 and another x11. Seems to me that a similar approach with x2 followed by x5 might be worth trying. Note that he does use a crystal as a filter on the output. I intended to try this approach myself last fall, but got distracted before the actual experiments. I still plan to try it soon. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
