Dan,
Do you have a schematic? I don't understand the description you provided.

Only thing I have Flip Flops but no AND Gates to try this now.
Anyways the LO IN is phase shifted

The switches that are used are linear devices. The output is
linearly related to the RF/IF input, but multiplied by a square wave
whose amplitude takes on only the values 0 and 1. This means that the
output of the QSD switches can vary in amplitude from 0 to
Hi Patrick,
So the working must be something close to:
* analytic mixing of I (with cos(wt) and sin(wt))
* analytic mixing of Q (with cos(wt) and sin(wt)),
At this level there are 4 components.
* sum et difference of components (I don't go into
details) will give two new components in
Hi Alberto,
Do you mean AD9954 or AD9854... ?
In my opinion the AD9954 does not provide I/Q outputs.
Best regards,

yes, I made a typing mistake, as already acknowledged in a previous
