Soliton decay in a composite right- and left-handed transmission line periodically loaded with Schottky varactors, termed a Schottky CRLH line, is characterized to obtain broadband envelope pulses. When the three waves in the line satisfy the wave-number and frequency resonance conditions, they are governed by the three-wave resonant interaction equation, which have solutions that exhibit soliton decay, i.e., the decay of the highest frequency envelope into those carried by the other two frequency solitons. Due to the left-handedness, solitons resulting from the decay can have much smaller width than the incident envelope. This paper discusses the potential of a Schottky CRLH line as a generator of broadband envelope pulses.
