Abstract :
A monolithic, photoconductive, ultrawideband RF radiating device has been successfully demonstrated. This device integrates the functions of energy storage, switch, and antenna onto a single semi-insulating GaAs wafer substrate so that the electrostatic energy storage in the device directly converts into ultrawideband RF radiation. Pulse biasing the device to +2 kV and -2 kV, and subsequently triggering the device resulted in peak power intensities as high as 14.8 W/cm at a distance of 40 cm.<>
