Abstract :
A high-power L-band PIN diode switch is described. The design uses 16 high-voltage PIN diodes in a novel coaxial structure. The switch has been tested to 100 kW peak power. Insertion loss is less than 0.25 dB, and isolation is greater than 25 dB across 14% bandwidth. The switch incorporates unique design features that allow use of high-voltage PIN diodes which were originally designed for much lower frequencies. An integral driver produces switching times under 10 mu s and includes built-in fault detection.<>
