Abstract
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.
Claims25
A method for generating an ultra-wideband (UWB) pulse, the method comprising the steps of:
- receiving an input signal comprising at least one pulse, the at least one pulse having a rising edge and a falling edge;
- varying the rising edge and the falling edge of the at least one pulse to generate a tuned pulse;
- differentiating the tuned pulse to form a Gaussian pulse;
- and
- differentiating the Gaussian pulse to form a monocycle UWB pulse.
A pulse-duration tunable ultra-wideband (UWB) pulse generator comprising:
- a variable edge rate pulse compressor;
- a Gaussian pulse former coupled to the variable edge rate pulse compressor;
- and
- a differentiator coupled to the Gaussian pulse former.
