(1) Sensitivity can be traded for current consumption by setting MDMCFG2.DEM_DCFILT_OFF = 1. The typical current consumption is then reduced by approximately 2 mA close to the sensitivity limit. The sensitivity is typically reduced to –109 dBm.
(2) Sensitivity can be traded for current consumption by setting MDMCFG2.DEM_DCFILT_OFF = 1. The typical current consumption is then reduced by approximately 2 mA close to the sensitivity limit. The sensitivity is typically reduced to –102 dBm.
(3) MDMCFG2.DEM_DCFILT_OFF = 1 cannot be used for data rates ≥ 250kBaud.
