Please take no offense but do you really understand what you are trying to do?By the way, how do I POWER RF systems? Is there anything that con hold a battery and use it to run an RF system? And is it adjustable?
It's like asking "how do I drink a beer bottle" "do I hold it upside down and let the liquid flow into my mouth, can I adjust the flow of beer? "
I would really suggest explaining what you are doing fully and what you aim to do, that is the only way you will get a meaningful answer and maybe even learn something. In case you think you have a novel idea and are reluctant to share , I would suggest that cannot be the case given you ask such basic questions that show your lack of understanding in the field.
