abstract = "The generation of radiofrequency through Nonlinear Transmission
Lines (NLTLs) have been investigated as an alternative way to
build RF generators for application in telecommunication, medical
and defensive electronic countermeasures systems. Two main
configurations of NLTLs were reported in the literature: discrete
lines that comprise a network of LC sections built with nonlinear
components and the gyromagnetic line that consists of a coaxial
transmission line loaded with ferrite-based magnetic cores.
Gyromagnetic lines produce high voltage microwave oscillations
with frequency ranging from few hundred of MHz up to less than 10
GHz requiring, however, an external magnetic polarization. On the
other hand, discrete lines are suitable for RF generation in a
lower frequency range from a few MHz to hundreds MHz, having a
better prospect for use in compact systems. Capacitive NLTLs
require the use of components that present voltage dependence
behavior of the capacitance as ceramic capacitors or special
diodes. While lines built with ceramics capacitors show a maximum
operating frequency around tens of MHz requiring high input
voltage, the use of silicon varactors diodes allows the
construction of low voltage lines, nevertheless by using carbide
silicon Schottky diodes the output of a capacitive NLTL can
provide a few kV of oscillation peaks. This paper presents some
experimental results that show the development of the capacitive
NLTLs at the Plasma Laboratory (LABAP) of the National Institute
for Space Research (INPE) in Brazil. The analysis of the
experimental results points that performance limits of capacitive
NLTLs are closely related to the characteristics of the nonlinear
component used in their construction and leads to the conclusion
that an improvement of their performance requires the development
of new nonlinear components, which present simultaneously
nonlinear capacitance to voltage behavior, low losses and thermal
stability.",
