ABSTRACT:
A system and method are disclosed for controlling transmitter output levels in a wireless communications device. The system comprises: a transmitter configured to accept an adjusted transmit bias control value and to supply a transmitter output level in response to the adjusted transmit bias control value; and a gain control circuit configured to supply the adjusted transmit bias control value in response to a transmitter output measurement and to a reference. The gain control circuit comprises a measuring circuit configured to accept the transmitter output level and to supply a transmitter output measurement, a table of initial transmit bias control values cross-referenced to transmitter output levels, the table configured to accept a transmitter output level selection and to supply an initial transmit bias control value in response to the transmitter output level selection, and, a compensator configured to accept the adjusted transmit bias control value and the initial transmit bias control value and to supply a compensated transmit bias control value based on a difference between the adjusted bias control value and the initial transmit bias control value.
