Abstract
A subscriber unit and method for wireless communication that dynamically adjusts RF amplifier operating bias for the subscriber unit's transmitter in response to a power control signal. The invention provides high-efficiency RF power amplification for applications where the available power source is limited. The invention uses a power control signal resident in wireless communication system architectures with a detector and voltage to current converter to arrive at a dynamic amplifier operating bias.
