    Abstract: A method and system for producing an adjustable resistor with a set resistance for adjusting quiescent current in a GaN transistor in a power amplifier. A quiescent current on the GaN power amplifier is measured via a test probe from a microcontroller unit on a test fixture. A resistance value is determined for output of a voltage bias value to adjust the quiescent current of the GaN transistor in the power amplifier. The resistance value is stored in an electronically adjustable resistor. The adjustable resistor is coupled to an output voltage circuit to provide voltage at the voltage vias value to a voltage bias input of the power amplifier.
