Hi, Most of wireless receivers dynamic range varies from 60 - 90 dBm. Dynamic range is entireley controlled by programming the individiual gains of LNA, Mixer and VGA's. My question is how to detect the input signal strength in order to have programmable gain settings so that ADC has the required dynamic range. How the receiver identifies the input signal strength (across the dynamic range) to set the rx chain gain automatically so that ADC receives the required signal?
Thanks.
