Abstract :
The GaAs Nonlinear Transmission Line (NLTL) is a transmission line loaded by reverse-biased Schottky diodes. Through generation of shock waves on the NLTL, we have generated stepfunctions with amplitudes of several volts and ~1 ps falltimes. NLTL-strobed diode sampling bridges have attained bandwidths beyond 300 GHz. Soliton propagation on the NLTL can be used for picosecond impulse compression and broadband mm-wave frequency multiplication. Applications include millimeter-wave network analysis both on-wafer and in free-space.
