Abstract: A system including a low noise amplifier is provided. The system further includes a coarse attenuation circuit coupled to an input of the low noise amplifier and configurable to attenuate an input signal by a coarse attenuation interval. The system also includes a fine attenuation circuit coupled in feedback with the low noise amplifier and configurable to attenuate the input signal by a fine attenuation interval, wherein the fine attenuation interval is less than the coarse attenuation interval.
