Abstract

The Army Research Laboratory (ARL), in collaboration with the Air Force Phillips Laboratory, has been developing the fabrication process for lateral topology, high-power photoconductive semiconductor switches (PCSS) used in phased-array, ultra-wideband (UWB) sources. This work presents issues associated with the development of these switches. First-generation devices (1.0 cm gap spacing) have been shown to achieve sub-nanosecond risetimes, working hold-off voltages of 50 kV, switched currents of 333A into a 75 Ω load, and lifetimes in excess of 2×106 shots at 10 Hz. Later generation devices (0.25 gap spacing) operate at 20 kV and 1 kHz, with improved risetimes, jitter characteristics, and trigger requirements.
