T_A = 25°C, VDD = 3.0 V if nothing else stated. All measurement results are obtained using the
CC2510EM reference design ([1]).

proportional to crystal frequency (given values assume a 26.0 MHz
crystal).

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 TEST2 and
TEST1 (see Page 222). The temperature range is then from 0^oC to 85^oC.

dBm The RX current consumption can be reduced by approximately 2.2 mA
by setting MDMCFG2.DEM_DCFILT_OFF=1. The typical sensitivity is then

The sensitivity can be improved to typically −100 dBm with
MDMCFG2.DEM_DCFILT_OFF=0 by changing registers TEST2 and
TEST1 (see Page 222). The temperature range is then from 0^oC to 85^oC.
