Patent ID: 8014467

Claim:
A method for producing an outgoing radio frequency signal by a radio transceiver, the method comprising: producing an outgoing digital signal having a digital gain; producing an analog transmit path signal to an analog transmit path based upon the outgoing digital signal; determining a plurality of pre-distortion settings that correspond to a plurality of analog transmit path gain settings; determining a desired total transmit path gain; setting the total transmit path gain to a first gain level by: setting a first analog transmit path gain one of a plurality of specified settings; and setting the digital gain so that, when added to the first analog transmit path gain, the desired total transmit path gain is produced; applying a first pre-distortion setting of the plurality of pre-distortion settings that corresponds to the first analog transmit path gain to counteract distortion that is caused by at least one of a plurality of modules in the analog transmit path; determining to adjust the transmit path total gain to a second gain level; adjusting a digital gain only if second gain level is within a specified digital gain range in relation to the first analog transmit path gain setting; when the second gain level exceeds the specified range, setting a second analog transmit path gain and applying a second corresponding pre-distortion setting; and adjusting the digital gain, if necessary, to provide the second gain level.
