| Abstract: | Based on the avalanche of a bipolar RF transistor,a ultra-wideband(UWB) narrow pulse generator with dual parallel structure was designed.Circuit and its avalanche principle were analyzed,the ADS 2008 was used for the design and simulation,the broadband matching problem was discussed,and the RF PCB was made.UWB narrow pulse generator test results show that: single-cycle bipolar pulse width is 981.3 ps,and the pulse amplitude peak value is 3 V. |
