It is also called snap off diode or charge storage diode or memory varactor and has a variety of uses in microwave electronics as pulse generator or parametric amplifier.

Step recovery diode pulse generator circuit. In electronics a step recovery diode srd is a semiconductor junction diode having the ability to generate extremely short pulses. Why ultra fast recovery diodes. The main constraint of the srd pulse generator design is the limited minimum pulse width of the generated pulse which is determined by the parameters of the srd.

The output waveforms of this devices give the resemblance of comb teeth. Simulated results validate the design. It can be used as pulse generator or parametric amplifier.

The dsr diode pulse generator depicted in fig. 8 consists of two circuits with a fast power transistor q1 eg. Consequently srds are primarily used for lower uwb bands up to about 5 ghz.

It is used in comb generator for generating multiple harmonics of its input signal. Con ventional srd based pulse generators usually employ an srd to generate a pulse with picosecond rising edge which de. The pulse generator uses a single step recovery diode to provide a truly balanced output.

The output pulse width and amplitude can be improved using mesfet amplication and compression circuits 10. Jim williams pulse generator duration. Two versions of the circuit with lumped and distributed pulse forming networks have been tested.

The step recovery diode srd is a rather specialist device that finds a number of applications in microwave radio frequency electronics. Among them the step recovery diode srd approach 46 features simple circuit design while providing picosecond pulse generation capability. The ability of step recovery diode to generate sharp pulses makes it appropriate to use as harmonic generators for generating different 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. The first circuit is composed of inductive energy storage l1 and the second circuit is composed of a capacitive storage c2 inductive storage l2 and dsr diode d1 connected in parallel with the load resistor r1. It is used in a frequency synthesizer.

Step recovery diode as harmonic generators. 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. 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 diode biasing is integrated with the switching circuitry to improve the compactness of the design. It is used in voltage controlled oscillators. By different techniques 3.
