Default Re: SSB Signal Generator

Hi Jeremy.... The filter was "copied" from the Minikit DDS Module, and as far as I remember I borrowed the componentrs from the module I purchased.... The reason I made my own was that the board area was far too big with wasted space for tracks that were totally un needed....... I did buy some more inductors to enable me to make more modules, as and when... I did buy the AD9951 and I have the software to run it..however it seemed such a waste of performance when I am only running up to 10M + I.f.... as it is rather expensive... but if that is what is needed..
I had 5 pcb's based on the 9951 made in China,
But for the moment..... could I please accept your offer... and see how it goes.
I was planning on using the 9850 for HF and the 9951 for VHF.

I think a suitable LPF + equaliser design could be fitted to your existing DDS board or maybe you could use this info for a future DDS board? eg for a test signal generator that needs to be flat across 0-40MHz for example.
I have no problems relaying the pcb......as you may know I have facilities here to make most pcb's,
