Abstract:
A radio frequency (RF) signal is attenuated using first (220) and second (241) attenuation elements. In one embodiment an initial overall attenuation of the RF signal is set using both the first (220) and second (241) attenuation elements during a calibration period. The initial overall attenuation of the RF signal is adjusted using only the first attenuation element during a normal operation period. In another embodiment the initial overall attenuation is determined and is provided using either, only the first attenuation element (220) or both the first attenuation element (220) and the second attenuation element (241) based on a value of the initial overall attenuation.
