abstract = "Dielectric nonlinear transmission lines (NLTLs) have demonstrated
great potential in RF generation. Their main characteristic is
that they do not require an electron beam to operate. However,
there are some key points in their operation not clarified yet.
For instance, they generate output oscillations with frequency at
half the line Bragg frequency for a high number of sections
(n>30); however, for smaller n (=10) this frequency appears to be
near the Bragg frequency1. In this work, it will be demonstrated
that this effect has to do with the spreading of train of solitons
travelling through a long line (i.e. with a high number of
sections). In addition, it will be shown that for a line with
higher n, the nonlinearity factor k of the dielectric can be very
close to unity, which means that capacitors with more stable
capacitance can be used. This effect has been observed in
practice, as it is easy to produce a train of solitons with higher
amplitudes for a line built with a large number of sections2.
Finally, the points discussed above will be checked experimentally
by measuring the standard FFT of the signal along a varactor diode
NLTL made with 30 sections, operating at the output frequency
around 50 MHz.",
