Field Plate Devices for RF Power Applications

Analytical Field Plate Model for Field Effect Transistors

“…Introduction of field plates into AlGaN/GaN HEMTs has allowed RF output power densities greater than 40 W/mm [6] and breakdown voltages greater than 1000 V to be achieved [7]. Despite the wide adoption of field plates, simple general design rules have not been clearly developed since the majority of field plate understanding comes from finite element simulations [5], [8]. Although finite element simulations are useful for field plate optimization, design equations must be fitted to simulated data [9] and are typically only valid over the simulation space investigated.…”
