Abstract:
1. A method for controlling a radio frequency (RF) transmitter that includes one or more amplification stages, the method comprising: defining a range of transmit power levels over which the transmitter is required to operate; determining a statistical distribution of a typical operational profile of the transmit power levels in the range that is expected to occur during use of the transmitter; dividing the range into a plurality of sub-ranges based upon the statistical distribution and determining, for each sub-range, one or more operational settings of at least one of the amplification stages; and configuring the transmitter to determine a target power level of an output RF signal during the use of the transmitter and to apply the one or more operational settings depending upon the sub-range in which the target power level falls.
