Thanks and indeed I do need filters that I have not experimented with and
in that respect this would be more like some of the circuits discussed here
on time-nuts.
I am using nice controlled delay lines and at $66 each thats pretty
un-attractive.
But hey when you get them for 50 cents at a ha
Hi Paul,
It isn't that it is bad, it is just that 5 and 15MHz products at
8 to 10dB down isn't very encouraging.

Experimenting with a 74ls86 XOR doubler for 5 to 10 Mhz. Typically this
would use a 90 degree phase shift to the other gate. The gate acting as a
mixer to produce 10 Mhz.
The reason to experiment is that I have noticed most of the doubler
discussions take a 5 Mhz square wave filter it to a sine wav
