A short-pulse generator for UWB applications
Sedláček, Matyáš ; Pítra, Kamil (oponent) ; Štumpf, Martin (vedoucí práce)
This master's thesis is concerned with the analysis and design of a short-pulse generator. It focuses on the utilization of step recovery diodes and reactance-based circuit elements. A model of the SRD for the use in simulation is tuned. A pulse shaping network (PSN) is designed, the properties of which are described via parametric analysis. Consequently, aiming at improving the output characteristics of the device, possible modifications to the circuit are explored, e.g., the inclusion of transmission line stubs. A PSN driver and supply circuits are designed. The pulse generator is powered by a battery, to comply with portability and energy self-sufficiency requirements. The properties of the manufactured generator are then tested via measurements.
