Rx band filter response compensation (GSM)

Prerequisites

Rx calibration must be performed before the Rx band filter response compensation.

Context

On each GSM Rx band, there is a band filter in front of the RF ASIC front end. The amplitude ripple caused by

these filters causes ripple to the RSSI measurement, and therefore calibration is needed.
