+In order to achieve optimal amplification from the LNA, a digitally-stepped attenuator (DSA) is placed preceeding the LNA to attenuate any signal over a specific saturation threshold. After the signal is amplified, the output is coupled into a power detector (PD) circuit, which is then fed into an ADC and back into the DSA to drive the signal attenuation. Once the power detector is able to realize oversaturation at the output, it will drive the DSA to further attenuate the signal, reducing the power output.
