AGC strategy

AGC-amplifier is used to maintain output level of the receiver in certain range. AGC has to be set before each received burst, to do this pre-monitoring is used to give an estimate ofthe signal level.

There is 50 dB accurate gain control (10 dB steps) and one larger step (—30 dB) in LNA. LNA AGC step size depends on channel with some amount.

RSSI must be measured accurately on range -48...-110 dBm. At levels higher than -48 dBm the RX level reported by the MS to the base station is always 63.

Production calibration is done with two RF-levels, the LNA gain step is not calibrated.
