This question is already answered in SWRA640. You must follow the recommended RF configuration options in that document. For smallest size, single ended RF output configuration is the best option.

Hi,

Thanks for your reply.

So single end is best solution, what about Band Pass Filter? Should we add this? Will it be helpful for EMI testing?

Bandpass filtering is included in the reference design. No additional circuitry is needed.
