Linearized front-end operation using information from baseband circuit

Abstract

Systems and methods for front-end linearization using information from a baseband circuit are disclosed. In one aspect, a baseband circuit provides information to a front-end module that uses the information to adjust operating parameter settings, such as how an analog predistortion (APD) circuit or power management integrated circuit behaves, to provide more linear operation of the front-end module across the frequencies of interest. In exemplary aspects, the front-end module may receive raw information from which the front-end module determines what changes should be made. In alternate exemplary aspects, the baseband circuit provides instructions or coefficients that are then used by the front-end module to make the changes. In either event, the front-end module may optimize operation to reduce power consumption and provide more linear operation so that the transceiver may better operate within the parameters of a given wireless protocol.
