Frequency response of a resonant dielectric amplifier

A fundamental limitation on the steady-state signal frequency response of a series-resonant dielectric voltage amplifier is the time required for the resonant circuit to adjust to a change in tuning. This paper analyzes this limitation for the case where nonlinear resonance effects may be neglected. Typically, this limitation may require that the power or carrier frequency be several hundred times the highest signal frequency, if the gain of the amplifier is to be constant.
