CC1101
Parameter
Min Typ Max Unit Condition/Note
868 MHz, 250 kBaud data rate, sensitivity optimized, MDMCFG2.DEM_DCFILT_OFF=0
(MSK, 1% packet error rate, 20 bytes packet length, 540 kHz digital channel filter bandwidth)
Receiver sensitivity
–94
dBm Sensitivity can be traded for current consumption by setting
MDMCFG2.DEM_DCFILT_OFF=1. The typical current
consumption is then reduced from 19.2 mA to 16.9 mA at
sensitivity limit. The sensitivity is typically reduced to -91 dBm
Saturation

dBm
Sensitivity can be traded for current consumption by setting
