主　　题：pulse generator ultra-narrow step recovery diode(SRD) pulse shaping circuit 

摘      要：Two new kinds of ultra-narrow trigger frequency alterable picosecond pulse generator are *** can produce positive pulses and the other can produce negative *** two pulse generators are subdivided into three parts:signal driving circuit,differentiator network and pulse shaping *** 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 *** of the components are ready-made and *** can be applied in ultra-wideband(UWB) communication system,such as transmitters and receivers.
