Abstract
An additional control voltage is used to adjust then operating point of a power amplifier. The amplitude of the control voltage is a measure of the maximum gain needed during the current time slot and which is already provided to the power amplifier before the beginning of the active time slot. This enables an individual adjustment of the operating point so that the power consumption can be reduced.
Claims25
A method for optimizing an operating point of a power amplifier in a mobile station, which comprises:
- using control signals to adapt an operating point of a power amplifier to a maximum power gain that is needed within a time slot of data transmission, the control signals including a first control signal for setting the maximum power gain and a second control signal for initiating generation of the operating point, wherein the maximum power gain and the operating point are switched over during a transition phase between successive active time slots.
In combination with a power amplifier that has an operating point and that is located in a mobile station, a device providing control signals for adapting the operating point of the power amplifier to a maximum power gain needed within a time slot of data transmission, the control signals including a first control signal for setting the maximum power gain and a second control signal for initiating generation of the operating point, the maximum gain and the operating point being switched over during a transition phase between successive time slots.
