Hi If you want to drive out of a 50 ohm source into your 50 ohm load *and* get 5V into the load … that’s a fancy amp. 10V power and some careful work to get it going.
If you just want to get roughly 5V into a 50 ohm load, then it’s a matter of how many gates you decide to parallel. If you go with “32 ma” drivers, you should be able to get it done with 8 of them in parallel. Drive them all off of a single dedicated fast gate that’s on the same supply. Probably best to stuff a 20 or 30 ohm resistor in series with each of the outputs. If it’s *got* to be a full 5V, don’t use the resistors.
