A simple picosecond pulse generator based on a pair of step recovery diodes lianfeng zou shulabh gupta christophe caloz abstract a picosecond pulse generator based on a pair of step recovery diodes srd leveraging the transient response of the srd pn junction and controlling the pulse width by a resistor is proposed.

Step recovery diode pulse generator.

The diode is also capable of working at moderate power levels and this gives it a distinct advantage over some other radio frequency technologies that. Integral 50 ω sma f step recovery diode outputs 60 ps transition time. 1 μs to 1 s internal clock period 3 ps rms jitter relative to external trigger 20 db 10 ghz sma m f attenuator included with step recovery diode outputs. Dual 2 5 to 6 v variable amplitude outputs 1 ns in 1 ps steps timing deskew.

Subnanosecond step recovery diode pulse generator srd differential output voltage 12 8 v rising time. The step recovery diode finds uses in a number of different roles including very short pulse generation ultra fast waveform generation comb generation and high order frequency multiplication. The ability of step recovery diode to generate sharp pulses makes it. The range of cut off frequency of step recovery diode is from 200 ghz 300 ghz.

4 ch differential pulse generator 2 ch srd integral 50 ω sma f step recovery diode outputs 60 ps transition time dual 2 5 to 6 v variable amplitude outputs 1 ns in 1 ps steps timing deskew 200 ns to 4 μs pulse width 1 μs to 1 s internal clock period 3 ps rms jitter relative to external trigger 20 db 10 ghz sma m f attenuator included with step recovery diode outputs 2 ch td. It is also called snap off diode or charge storage diode or much less frequently memory varactor and has a variety of uses in microwave electronics as pulse generator or parametric amplifier. In electronics a step recovery diode srd is a semiconductor junction diode having the ability to generate extremely short pulses. The pulse generator comprises three parts a step recovery diode a field effect transistor and a schottky diode used to eliminate the positive and negative ringing of pulse.

Thus this high range of cut off frequency enables the diode to be used as a multiplier for circuits operating at a frequency of about 10 ghz. When diodes switch from forward conduction to reverse cut off a. Coupled slotline hybrid sampling mixer integrated with step recovery diode pulse generator for uwb applications abstract. A step recovery diode also known as a snap off varactor is a silicon or gallium arsenide p n junction diode of a construction similar to that of the varactor diode.

Step recovery diode as harmonic generators. It is an epitaxial diffused junction diode designed to store charge when it is conducting with a forward bias. 180 ps pulse width.
