ABSTRACT:
The combination of a photoconductive switch coupled to an energy storage ice wherein the switch is comprised of photoconductive semiconductor material while the energy storage device comprises a radio transmission line including a different material, i.e. a dielectric storage medium. A photoconductive semiconductor gallium arsenide switch is embedded in a circular disc of dielectric material with upper and lower layers of continuous radial metallization configured in a circular pattern located thereon. The upper layer of metallization includes an apertured grid adjacent one surface of the switch, while the outer conductor of a coaxial output signal line is connected to the metallization layer on the opposite side with the inner conductor thereof passing through the dielectric layer to the undersurface of the semiconductor switch. A variation comprises the upper and lower metallization layers being formed in the shape of a plurality of discrete straight line segments or strips which extend radially outward from the center and thus forms a quasi-radial structure.
