Patent ID: 7764141

Claim:
A non-linear waveguide, comprising: a transmission line including a first conductive line and a second conductive line; a first bias voltage supply connected with the transmission line; and one or more pairs of diodes connected between the first conductive line and the second conductive line, the one or more pairs of diodes including: a first diode having an anode connected with the first conductive line and a cathode connected with the second conductive line, a second diode having a cathode connected with the first conductive line and an anode connected with the second conductive line, and a second bias voltage supply connected between the anode of the second diode and the second conductive line; and a signal generator connected to the transmission line to transmit an input voltage signal that varies with time; wherein the one or more pairs of diodes shortens a rise time and a fall time of the input voltage signal as the input voltage signal is transmitted through the transmission line to generate an output pulse signal.
