A Physics-Based Nonlinear Model of Microwave P-I-N Diode for CAD

A p-i-n diode model for switching and limiting applications is presented. The model allows to simulate the I-region store charge effect that governs the impedance-frequency characteristic of the diode. The model also includes recombination phenomenon in the heavily doped region and junctions effects. The diode model has been implemented in a commercial circuit simulator and validated with a good agreement by measurement results
