TRF370417 / sideband suppression with differential LO input

The performance of SBS is roughly equivalent between driving SE or driving differential. The only major advantage is (potentially) delivering additional power to the device with differential and there can be some variation due to LO power that is depicted in the graph. --RJH

Hello RJH

Thank you for the reply.
Are there the graph or the actual data which you can share with us?

Hello RJH san,

Sorry for bothering you.
Are there the actual data at the LO differential input ?
If there is no data, please let me know it.

Hello RJ

Can you please advise if you expect degradation in the carrier suppression when using single ended LO input?

You can assume that the input power is the same (balanced/single ended input)

Thanks

There is no degradation.  D/S characterization was done with SE input.  The biggest variation is related to the LO amplitude signal.  Refer to the datasheet for the plots of Carrier Suppression vs. frequency over LO drive level.

Thanks!
