IPC: H04B7/005
Filed: 2006-01-12
Abstract: The present invention comprises a method and apparatus for continuously controlling a gain of an amplifier circuit while switching between open-loop and closed-loop power control. A control circuit controls the gain of the amplifier circuit during open-loop and closed-loop power control modes based on selected references. Before the switch from open-loop to closed-loop power control, the control circuit determines a closed-loop reference based on a power measured at the amplifier circuit output before the switch. After the switch, the control circuit controls the gain of the amplifier circuit based on the determined closed-loop reference. Before switching from closed-loop to open-loop power control, the control circuit generates a difference between a current open-loop reference and a previous open-loop reference. After the switch, the control circuit controls the gain of the amplifier circuit based on an open-loop gain control signal generated by applying the difference to a previous closed-loop gain control signal.
