Preliminary Specifications for the Pre-driver Amplifier to be used in the PS Transverse Damping System

The 3 kW amplifier (PS/RF/Note 2001-005, M. Paoluzzi) that feeds the transverse kicker needs a driving circuit to fulfil some needs. In particular, it must adapt its gain to the amplifier gain change when switching from high to low power operation. High power will be used for a short time to cancel the injection oscillations. It also needs to provide some test inputs and outputs to measure the transfer function of the system. The other required specifications are described below.
