Abstract: Each radio of a plurality of radios includes a plurality of variable gain stages connected in series. The radio further includes at least one power detector connected to the variable gain stages, a temperature sensor, and a processor for controlling the variable gain stages in-service based upon the at least one power detector, the temperature sensor, and stored frequency and power compensation values. A method for calibrating each radio includes generating frequency compensation values for at least one first variable gain stage by supplying a first calibration signal swept in frequency while maintaining the radio at a constant temperature. The method further includes generating power compensation values for at least one second variable gain stage by supplying a second calibration signal swept in power level and while maintaining the radio receiver at a constant temperature.
