Just curious, I'm not an expert on RF, but where does the LNA fit in here? It seems like you could do the conversion from single-ended to differential using an LNA if you were already using one.
I've only played with single-ended designs, so this is something completely different for me.

The bandpass filter and LNA would proceed this circuit. Most LNAs I'm familiar with are single ended output. Differential input is a bit of an oddity for an RF interface. I'm certain someone had a reason.
In our instance we will have a bandpass filter followed by an LNA followed by a 1:4 splitter for the four receivers. Each receiver will require some form of single end to differential converter.
