Symbol Description Conditions Min Typ. Max Unit
ACR_LCW
Adjacent channel rejection
FRF = 903 MHz
Interferer is 1.5*BW_L from the
wanted signal centre frequency 1%
PER, Single CW tone = Sensitivity
+ 3dB
SF = 7 – 60 – dB
SF = 12 – 72 – dB
IMR_LCW
Image rejection after
calibration
1% PER, Single CW tone = sensitivity
+ 3dB
– 66 – dB
FERR_L
Maximum tolerated frequency
offset between transmitter
and receiver, no sensitivity
degradation, SF6 thru 12
All BW, +/–25% of BW
The tighter limit applies (see
below)
– ±25% – BW
Maximum tolerated frequency
offset between transmitter
and receiver, no sensitivity
degradation, SF10 thru 12
SF = 12 –50 – 50 ppm
SF = 11 –100 – 100 ppm
SF = 10 –200 – 200 ppm
SF = 10 –200 – 200 ppm
