Experimental Characterization of Nonlinear Pulses in Coupled Schottky Transmission Lines

We experimentally investigate the properties of nonlinear pulses in coupled transmission lines with regularly spaced Schottky varactors. The c and π modes are different propagation modes that can be developed on a coupled line. Time-domain measurements show that both modes support soliton-like pulses due to the presence of the Schottky varactors; small c-mode pulses are generated by colliding two π-mode pulses traveling in opposite directions. Moreover, we discuss the relationship of the amplitude of the newly generated c-mode pulses with different bias voltages and π-mode-pulse amplitudes.
