摘要：  Two new kinds of ultra-narrow trigger
frequency alterable picosecond pulse generator are presented. One
can produce positive pulses and the other can produce negative
pulses. The two pulse generators are subdivided into three parts:
signal driving circuit, differentiator network and pulse shaping
circuit. The pulse shaping circuit is made of step recovery diode
(SRD) and short-circuit microstrip line. A positive pulse with width
of 54 ps (50% ---50% ), rising time of 30 ps (10%  ---90%  )
and falling time of 32 ps (90%  ---10%  ), and a negative pulse
with width of 54 ps (50%  ---50%  ), rising time of 30 ps
(90%  ---10%  ) and falling time of 30 ps (10%  ---90%  ) are
achieved in simulation. All of the components are ready-made and
inexpensive. They can be applied in ultra-wideband (UWB)
communication system, such as transmitters and receivers.
