Hello,
I followed with some interest a discussion about a NIST doubler circuit using matched FET's and I was wondering if you could get similar results using an analog multiplier chip from Analog Devices. It would seem that they take some care about device matching and have parts that work up to pretty high frequencies. Of course there would need to be some filtering employed. Oh, and I think those parts do pretty well with temperature. Also, when using a doubler that is rated in dBc how do you apply that number to get an expectation from a given starting dBc oscillator. So if my 10 MHz clock is -125dBc and I use the NIST circuit, what would I see at 20 MHz in dBc? thanks in advance, steve _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
