A model of tri-gate MESFET switch-additional gated switch is proposed. The model is based on the structure of the tri-gate MESFET switch device. The influence of the gate on the microwave signal is considered. It is suitable for the design of MMIC switch circuit and has good Broadband microwave characteristics. The measured values of the device are in good agreement with the simulated values of the model.
