When using avalanche transistors at high continuous repetition rates and particularly at large duty cycles, problems are encountered. Therefore, some desirable avalanche transistor parameters and some suitable basic circuit configurations are indicated. A triggerable pulse generator which operates at over 10 megacycles and produces pulse widths adjustable from a few nanoseconds to 40-percent duty cycle is described. These pulses are of low time jitter and are approximately rectangular with about 2-nanosecond rise and fall times at 50 ma on 125 ohms.
