                         behavior are essential for use in capacitive non linear 
                         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 a 
                         piezoelectric capacitor based on lead-zirconate-titanate (PZT) was 
                         characterized in a broadband frequency from 10 MHz to 1 GHz for 
                         use in NLTLs. Also three commercial ceramic capacitors made of 
                         barium titanate (BaTi03) were also assessed for comparison with 
                         the PZT capacitor. The characterization of materials consists of 
                         measuring the relative dielectric constant (real and imaginary 
                         parts) as function of the applied voltage and frequency to 
                         calculate the loss tangent of the material. The results showed 
                         that PZT material has a better performance for use in NLTLs than 
                         barium titanate because of its lower losses. As shown here, 
                         however, the use of PZT and barium titanate based materials in 
                         NLTLs are compromised by the self-resonant frequency of the 
                         capacitors due to the inherent parasitic inductance associated to 
                         the capacitor at high frequency.",
