sensitivity
−103
dBm The RX current consumption can be reduced by approximately 2.4 mA
by setting MDMCFG2.DEM_DCFILT_OFF=1. The typical sensitivity is then
−101 dBm.
The sensitivity can be improved to typically −105 dBm with
MDMCFG2.DEM_DCFILT_OFF=0 by changing registers TEST2and
TEST1(see Page 222). The temperature range is then from 0oC to 85oC.
