Hi Antonio and, welcome.
Although, you really don't need a router table to raise the panels, it makes the job easier. Your best bet would be to make your own table and buy a set of raised panel bits for 1/2" stock. I have a set from CMT and, I'm sure many other manufacturers offer the smaller sets, too. MDF dulls bits quickly, though. It may be false economy. (Seems to be a lot of that going around)
Have you considered using an inexpensive dado set, instead?
