abstract = "Nonlinear transmission lines (NLTLs) have been studied over the
past several years to generate high-power radio frequency signals.
Their operation consists of a lumped line based on the nonlinear
behavior of the LC section components, capacitors or inductors, as
a function of the applied voltage or current, respectively.
However, considering high-power signals, the application of these
devices using nonlinear ceramic capacitors as the capacitive
lumped lines are restricted to frequencies around 100 MHz since at
high voltages, parasitic impedances in the line structure limit
the maximum operating frequency. On the other hand, the use of
variable capacitance diodes has enabled the operation of NLTLs at
higher frequencies. This paper provides the results of a study of
NLTLs for RF generation based on silicon carbide Schottky diodes.
The principle of operation and its simplified theory are
presented. Initially, the voltage dependence of the diode
capacitance is modeled. Experimental and simulation results are
compared. Frequency oscillations around 200 MHz were generated.
The extraction of the radio frequency energy is realized, and the
radiation of the electromagnetic wave is performed using
double-ridged horn antennas. Finally, some parameters are
analyzed, and all results discussed.",
