Hello Rick!
I would like to see the ability to have independent U/V and L/S transponders operational simultaneously. If a single SDX lacks the power to accommodate this then I think we should consider two SDXs.
Two SDXes have always been the baseline. Again, this is in the report from Oct in Colorado last year. The spacecraft has completely changed since then, of course, but we listed two SDX modules and the wiring for them.

Short version: The matrix function is subsumed into the SDX modules.
To shed a bit more light, the SDX is designed with its own "matrix." There are two uplinks: U and L. The SDX can select either or both. It can send its output to V or S (or whatever the second downlink is now going to be) - or both.
At least, this is what we thought a year ago, and what we wrote up in the wiring harness report after the Colorado meeting last October.
