Bluetooth LE RF Performance
Bluetooth LE Receiver Characteristics—In-Band Signals
Parameter Condition
(1)
MIN TYP MAX Units
BT LE Operation frequency range 2402 2480 MHz
BT LE Channel spacing 2 MHz
BT LE Input impedance 50 Ω
BT LE Sensitivity
(2)
, Dirty Tx on -92.2 dBm
BT LE Maximum useable input power -5 dBm
BT LE Intermodulation characteristics Level of interferers. For n = 3, 4, 5 -36 -30 dBm
BT LE C/I performance Note:
Numbers show wanted signal-to-
interfering signal ratio. Smaller
numbers indicate better C/I
performance. Image = -1MHz
LE, co-channel
12
dB
LE, adjacent ±1MHz
0
LE, adjacent +2MHz -38
LE, adjacent –2MHz -15
LE, adjacent ≥ |±3|MHz -40
(1) BER of 0.1% corresponds to PER of 30.8% for a minimum of 1500 transmitted packets, according to Bluetooth LE test
specification.
(2) Sensitivity degradation up to -3dB may occur due to fast clock harmonics.

7.0 dBm
Vbat < 3V 7.0 dBm
BT LE Adjacent Channel Power |M-N| = 2 -51.0
dBm
BT LE Adjacent Channel Power |M-N| > 2 -54.0
(1) Bluetooth low energy power is restricted to comply with the ETSI 10-dBm EIRP limit requirement.
(2) VBAT is measured with an on-chip ADC that has an accuracy error of up to 5%.
