(1) All measurement results are obtained using the EM430F6137RF900 with BOM according to tested frequency range (see Table 49).
(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 -107 dBm
(3) See design note DN010 Close-in Reception with CC1101 (SWRA147).
(4) See Figure 24 for blocking performance at other offset frequencies.
(5) See Figure 25 for blocking performance at other offset frequencies.
(6) 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 -100dBm.
(7) MDMCFG2.DEM_DCFILT_OFF = 1 cannot be used for data rates ≥ 250 kBaud.
(8) See Figure 26 for blocking performance at other offset frequencies.
(9) See Figure 27 for blocking performance at other offset frequencies.
