Higher order mode power will be a major issue at the highest beam intensities. A conceptual design of the FCC RF system is proposed along with highlights of specific R&D topics to reach the design performance. Challenges related to RF structure design, RF powering and higher order modes are addressed. Breakeven point between bulk Nb and Nb/Cu technologies are discussed.
