Robust passive shaping network for impulse radio and UWB signal generator

This work presents the design, development and measurement of a robust passive pulse shaping network for UWB applications. Our approach is based on a novel symmetric hybrid-based topology. The general method to design this kind of shaping network is described. It demonstrates that by properly tuning the dimension of the hybrid topology one may compensate the unbalanced effects exhibited by a conventional T-junction shaping network topology. Microstrip technology is used to implement two pulse shaping networks. Measurement results show good agreement with simulation.
