Abstract: Techniques are provided for automatic gain control. A methodology implementing the techniques according to an embodiment includes imparting, by a first adjustable attenuator, a first attenuation to a received radio frequency signal to generate a first attenuated signal. The first attenuation is based on a first control signal. The method also includes imparting, by a second adjustable attenuator, a second attenuation to the first attenuated signal to generate a second attenuated signal. The second attenuation is based on a second control signal. The method further includes converting, by an analog-to-digital converter, the second attenuated signal to a digital signal and measuring, by a processor based system, the ratio of peak power of the digital signal to average power of the digital signal, to generate a peak-to-average ratio (PAR) value. The first control signal and the second control signal are generated based in part on the PAR value.
