A photoconductive switching device is disclosed that has an enhanced speed of response so that its closed low and open high resistive states are obtained in response to optical illumination in the less than nanosecond regime. The enhanced speed of response is achieved by neutron irradiation of a material preferably comprising GaAsSiCu. An application of the improved photoconductive switching devices is disclosed which allows the realization of a high power, frequency agile RF source topology.
