                         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.",
