PHEMT transistor models for accurate CAD of MMIC amplifier
Accurate modeling of microwave monolithic integrated circuits (MMICs) is very desirable for the reason of high fabrication costs of GaAs circuits. Designers are trying to achieve the ``first trial success`` to lower costs and accelerate the introduction
