... point in any general way. The second detail is that the Manley-Rowe relations
do not simply establish a limit to the efficiency of a varactor frequency converter;
they describe a fundamental characteristic of any pumped nonlinear reactance.

Mechanical varactors for capacitance changing are now used because their low
reliability. First attempts to use magnetron as electronic varactor were made in
the middle of 40-th [11. RF losses were so high, that idea was not realized.

RF and Microwave Passive and Active Technologies
Since the standard varactor model consists of a resistance in series with a
nonlinear capacitance, the elastance is used rather than the capacitance. This
simplifies the analysis and gives, generally, a better understanding of the
varactor.
