METHOD FOR ENVELOPE TRACKING MULTIPLE TRANSMISSIONS THROUGH A SINGLE POWER AMPLIFIER

摘要

A method is performed on an integrated circuit, for generating a composite envelope reference voltage for a plurality of transmit signals. The method includes, generating a composite baseband signal from a plurality of baseband signals, wherein the plurality of baseband signals represent a corresponding plurality of different transmit signals (402). The method also includes calculating a composite envelope signal for the composite baseband signal (404), and generating a composite envelope reference voltage from the composite envelope signal for use in powering a single power amplifier as the power amplifier transmits the plurality of different transmit signals (406).
