ABSTRACT:
Comb generators include a nonlinear transmission line (NLTL) having one or more NLTL sections. Each NLTL section includes one or more nonlinear elements and transmission line portions that provide transmission line dispersion. Typically, the nonlinear elements are Schottky diodes, and a pulse forming bias network is configured to establish Schottky diode bias conditions using a periodic signal that is input to the comb generator. For input periodic signals at frequencies between about 500 MHz and 1 GHz, output signals are produced having substantial power in frequency components at frequencies up to at least about 50 GHz.
