Abstract: A system and method for using an embedded microprocessor in an RF amplifier. The use of an embedded microprocessor avoids manual calibration. The Microprocessor collects initial amplifier performance data based on a set of parameters and calculates the needed corrections. The microprocessor can change levels within the circuit to achieve those operating points. The embedded microprocessor sets voltage levels with internal circuitry and communicates this information externally through a serial communication port, or the like, to allow a user to communicate with and look at the amplifier data and readjust the internal bias levels, as needed. Thus, the internal microprocessor provides for calibration, self-testing, and monitoring of the RF amplifier and also functions as an in situ bias and temperature compensation controller for use in the presence of temperature variation and provides bias sequencing control to protect against improper applied timing of voltage inputs to the amplifier.
