Limiting Amplifier and RSSI ( Received Signal Strength Indicator ).
The stage consists of a limiting amplifier chain with an RSSI detector. The inputs are internally coupled from the channel
selection filter which limits the noise bandwidth. A balanced DC offset correction loop, provides maximum sensitivity, and
ensures a short settling time upon power up.
An RSSI output provides a voltage proportional to the logarithm of the rectified input level. The rise time response of the
RSSI output and the peak hold is dependent upon the external circuit.

a. The RSSI relative accuracy is the deviation of the RSSI value from a best fit straight line fitted to several calibration points.
These points are determined for each part.
