RF Pulse Generation using Nonlinear Transmission Lines

RF frequency pulse generation using nonlinear transmission line (NLTL) is presented in this work. The NLTL implemented using combination of inductor and capacitor (LC). In this work inductor is used as linear element and varactor diode is used as a nonlinear capacitor. The linear LC elements in the transmission line circuit produce dispersion, while the nonlinear lumped elements (LC) produce the nonlinear characteristics. Dispersion and nonlinear properties are combined together to generate a high frequency pulse. NLTL is designed to operate at 39MHz. In this work design and analysis of NLTL is carried out using LTspice tool. Parametric analysis is done to optimize the network elements. Using optimized circuit elements 32MHz RF is generated.
