The present invention provides a single-stage tunable Ultra-Wideband (UWB) pulse generator, by creating and differentiating a variable edge rate signal. Edge rate variability is introduced by first applying a step recovery diode (SRD) to compress the edges of the source and then applying a simple RC network to adjust the edge rate. Next, the resulting signal is differentiated using microstrip transmission lines. The tunable generator resulting from this approach demonstrates a Gaussian and monocycle pulses with good symmetry and low distortion over the tunable range.
