An investigation has been made to determine the feasibility of using PIN DIODES AS SWITCHING ELEMENTS TO CONTROL 150 PS, 8 MW impulse signals. Single diodes in shunt and in series with a 50-ohm stripline were studied, as were series stacks of up to 8 diodes. It is found in the series configurations that good signal fidelity obtains in forward bias at all signal voltages, with insertion loss being a function of I region thickness. At higher signal voltages it is an even stronger function of the signal since diode conductance significantly increases with internal voltage stress.
