I have an RF device. I have an IR remote. I need something in-between to take an IR code and translate it to RF.

Are you just looking for an IR repeater? Those are everywhere. The "Terk Powermid" devices (re-sold under several brands including Radio Shack and X10) work fine for me, I own two sets.

Otherwise, you're talking about two incompatible systems (RF and IR) and there's not much you can do.
