9. Electrical Characteristics (Continued)
All parameters refer to GND, T
(For typical values: V
4839B–RKE–08/05
Parameters
Sensitivity variation FSK for the full
operating range including IF-filter
compared to T
SNR to suppress inband noise
signals. Noise signals may have any
modulation scheme
Dynamic range RSSI ampl.
Lower cut-off frequency of the data
filter
Recommended CDEM for best
performance
Edge-to-edge time period of the input
data signal for full sensitivity
Upper cut-off frequency data filter
Reduced sensitivity
