| Abstract: | The generation of ultra-short pulse is a crucial technology in UWB wireless application.A novel pulse shaping method is discussed in this paper as an option to tackle the phenomenon that the monocycle pulse does not comply with FCC regulation regarding the effective isotropic radiated power.For the wave and spectrum of one polycycle pulse,theoretical analysis is consistent with the CAD simulation results.A simple and reliable microstrip pulse generator has been designed,fabricated and tested by using step recovery diode.The testing result also confirms that the method in discussion has outstanding performance in generating polycycle pulse. |
| Keywords: | polycycle pulse shaping method SRD(Step Recovery Diode) |
