Abstract :
GaAs Schottky diodes varying in size from 40 mum to 400 mum anode periphery have been tested to assess their effectiveness as ESD protection devices in FET-based MMICs. ESD failure voltage is seen to increase linearly with diode size. While the capacitive loading of these diodes is too high for use in protection of most RF circuit ports, they have been shown to effectively protect sensitive DC logic circuits in E/D pHEMT switches.
