Hello
I found a modulator "SAMSUNG RMUP23855FG" from an old analog sat receiver, it work between channel 30 to 40 (550 - 650MHz), so how can I build an amplifier stage with transistors to obtain 100 to 500mW output power.

Camera and the modulator are remote controlled via a 2,4GHz system, (switch on/off) so it's necessary to have a minimum perturbations on 2.4GHz, and i would like to maintain a minimum video quality, it's possible ? how can i do this.

thanks
 
I'll skip the legalities.
There are no shortage of monolithic modules to do the job.
Something like a CA5815CS which is a broadband low power module for the task.

I've also used BFR96's in class A for a similar job, but that's a little more effort than just a black brick.
