Type your letters as two lines of text, both approximately the same length (i.e. two separate text objects). It's also probably a good idea to choose a font that has no descender for the J or Q, or just avoid using those letters.
Select the top text object, apply Object > Envelope Distort > Make with Warp. Choose the Arc setting, Bend 100% and set the Y distort as you like.
Repeat for the bottom line of text.
Rotate and move into position, and rotate both if required.
A rough example
Font choice will obviously make a difference, this one is Orbitron Black, which is quite square and blocky
