abstract = "Nonlinear Transmission lines (NLTLs) have been studied for high
power RF generation with good prospects of applications in
telecommand systems of small satellites (Cubesats), pulse radars
for remote sensing (SARs) and disruption of communications in
battlefield, [1], [2] for instance. Usually NLTLs employ barium
titanate (BT) ceramic-based capacitors or ferrite bead inductor as
nonlinear elements, denominated as capacitive or inductive lines,
respectively. On the other hand, a configuration that employs both
nonlinear elements (LC), known as hybrid line, is an efficient
approach for exciting soliton oscillations more easily than
inductive or capacitive lines. Other interesting aspect is that
numerous publications on NLTL with only one linear component are
easily found in the literature whereas just a few on hybrid lines
and only one considering line experimental tests. In view of that,
in this work a 30-section hybrid NLTL built using inductors and
capacitors of strong nonlinearity (2.2 nF BT ceramic capacitors
and 10 \μH ferrite bead inductors) will be described. For
the test, the line is fed by a negative input pump pulse generated
by a 1 kV discharge of a 0.75 pF storage capacitor via a fast 50
ns switching system composed by an IGBT switch and its gate
circuit driver. In the hybrid line tests, the soliton generation
packet obtained on the middle section had a frequency of the order
33.0 MHz, peak power of 13.0 kW and voltage modulation depth (VMD)
of around 700 V. For each single shot, approximately 10 RF cycles
with small damping were noted. The main conclusion from this
experiment is that with an improved proper design hybrid lumped
NLTLs may be used to achieve RF in the range of 100-200 MHz.",
