Generateur d'impulsions nanoseconde et circuit de mise en forme a transistors avalanche

Abstract

A pulse generator which operates at high continuous repetition rates and produces rectangular or exponential pulses is described. The circuit is all solid-state and uses avalanche transistor. At 5 Mc/s the pulse width is adjustable from 2 to 10 nanoseconds with a 0.5 nanoseconds rise time and 8 volt amplitude on 50 ohms. At 25 Mc/s exponential pulses are produced with 1 nanoseconds rise and 15 nanoseconds fall times.
