Cheng, “Nanosecond pulser based on serial connection of avalanche transistors,” International Conference on Measuring Technology and Mechatronics Automation ICMTMA 2010, Changsa, China, 2010, vol. A negative point regarding step recovery diodes is their not easy availability, due to the potential dual-use, with restrictions on their commercialization A.

2008.] a UWB pulse generator employing SRDs followed by a shape-forming network outputs a monocycle pulse, with amplitude of 25 V and pulse width of 500 ps. Machac, “Universal generator of ultrawideband pulse”, Radioengineering, vol. The use of avalanche transistors as UWB source is limited due to the repetition rate, which may potentially create thermal damage to the device, so step recovery diodes (SRD) are indicated, though operating at lower amplitudes. A pulse with rise time of 3 ns and amplitude of 2.5 kV is generated and extracted by means of a coaxial transmission line.
73–76.], a string of 22 avalanche transistors FMMT417 (connected as diodes emitter and bases short-circuited, breakdown voltage of 270 V), is powered up with a 6 kV DC voltage. Tan, “Research on high-repetitionhigh-voltage nanosecond rectangular pulse generator based on avalanche transistor,” 7th Asia-Pacific Conference on Environmental Electromagnetics CEEM, Hangzhou, China, 2015, pp. A chain of four series-connected power transistor (2N3055) were excited to enter into avalanche mode, generating a 666 V pulse which is connected to a 100 MHz bow-tie antenna A. It was not seen the radiated signal since the system had not been connected to a radiant system. The signal was visualized with a 1.5 GHz oscilloscope on a load resistor. 447–450.], with a total of ten stages and powered with DC voltages from 250 V up to 284 V. Zhao, “Comparative analysis on the fast rising edge pulse source with two kinds of avalanche transistor,” 2013 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference CSQRWC, Sichuan, China, 2013, pp. A Marx generator based on special avalanche transistors was analyzed in Q. Tian, “Design of electronic circuits of nanosecond impulser based on avalanche transistor,” 11th Int. 2008.], ground penetrating radar (GPR) A. Kassel, Germany: Kassel University Press. Fast pulse generators have several applications, such as electromagnetic noise generators, medical treatment, Ultra-Wideband (UWB) radars A.
