                         behavior are essential for use in capacitive nonlinear 
                         transmission lines (NLTLs) for RF generation. NLTLs have a great 
                         potential to generate solitons waves for high power microwave 
                         applications in mobile defense platforms and satellite 
                         communications. In this work the dielectric properties of four 
                         commercial ceramic capacitors (two radial and two SMD types) based 
                         on barium titanate (BaTiO3) were characterized in a broadband 
                         frequency from 10 MHz to 1.2 GHz for use in NLTLs. The 
                         characterization of materials consists of measuring the relative 
                         dielectric constant (real and imaginary parts) as function of the 
                         applied frequency to calculate permittivity and the loss tangent 
                         of the material. The SMD capacitors tested in this work showed a 
                         good performance in high frequency range with selfresonance 
                         greater than 1.0 GHz with lower losses and weak nonlinearity in a 
                         large frequency range, which is very suitable for applications in 
                         telecommunications systems such as in mobile phones, but not in 
                         NLTLs. On the other hand, radial capacitors are more suitable in 
                         NLTL applications because of their strong nonlinearity; however, 
                         their performance are compromised by the self-resonant frequency 
                         between their capacitance and the inherent parasitic inductance 
                         associated to the capacitor geometry and terminals, restricting 
                         their frequency range of operation for use in NLTLs up to 0.2 
                         GHz.",
