Abstract
A constant current bias approach that receives an input bias voltage and maintains a temperature independent constant current bias in a linear amplifier device. Integrated sense circuitry protects against unacceptable input voltages to guarantee bias stability. Fabrication in multiple semiconductor technologies and assembly into a single package allows for optimum cost and performance of DC bias and RF amplifier sections.
