Abstract
A radio frequency (RF) power amplifying system. The power amplifying system includes a power controller and power amplifiers comprising power transistors and bias circuitry. The bias circuitry provides current to the base of the one or more power transistors in such as manner as to automatically maintain the power transistors in substantially linear operation throughout the variation in voltage as supplied by the power controller.
