Abstract
Waveguide nonlinear signal processors include transmission lines defined on a substrate. A plurality of varactors or pairs of varactors are situated along the transmission line and are in communication with a signal conductor of the transmission line and one or more control conductors. A processor controller is configured to provide a control signal to the one or more control conductors to select operational characteristics of the varactors or pairs of varactors. In some examples, the varactors are diodes and a control signal is provided to select a diode current-voltage characteristic in order to limit or clip an input signal to positive and/or negative amplitudes. Alternatively, a control signal is configured to provide a selected spectral transmission bandwidth or propagation delay by selecting a varactor capacitance-voltage characteristic.
