Design of the PBS wideband RF system

In the framework of the LHC Injectors Upgrade project (LIU) the PS Booster (PSB) will undergo in depth consolidation and upgrade programs. Both injection and extraction energies will be increased and a substantial rise of the beam intensity will also occur. This note presents an analysis of what is required to cope with this new situation and describes the possible replacement of the existing narrowband, tuned RF systems covering the $\textit{h}$=1 and $\textit{h}$=2 frequency ranges by a system based on the wideband frequency characteristics of Finemet® magnetic alloy (MA) and solid-state amplifiers.
