MULTI-MODE SELECTABLE MODULATION ARCHITECTURE CALIBRATION AND POWER CONTROL APPARATUS, SYSTEM AND METHOD FOR RADIO FREQUENCY POWER AMPLIFIER

摘要

A control input signal (107) to select a modulation architecture is received. When a first modulation architecture is selected based on the control input signal (107), a time varying and substantially known baseband bias control signal is applied to a bias input (117) of a power amplification module (120) and a time varying and substantially known baseband modulation envelope signal is applied to an input (124) of the power amplification module (120). When a second modulation architecture is selected based on the control input signal (107), the time varying and substantially known baseband modulation envelope signal is applied to the bias input (1 17) of the power amplification module (120) and the time varying and substantially known baseband bias control signal is applied to the input of the power amplification module (120).
