[Amps] HV MOSFETs for RF

[John Lyles]

Hi Cathy,
For particle accelerator RF systems, we require linearity for some 
systems where the envelope of the RF pulse has ramped voltages. This is 
needed to capture particles such as ions and protons in a storage ring. 
Generally speaking for linear accelerators, linearity is required over a 
limited dynamic range, to adjust the RF voltage within 0.5% or less (and 
phase must be similarly maintained/locked). This sort of regulation 
would be over a few dB of dynamic range, but we typically use linear 
amplifiers to simplify things. Power efficiency is not top of the list 
of specs.
