Data Sheet

Test Conditions

Pin = −20 dBm, 2 CW interferers

FRF = 915 MHz, F1 = FRF + 3 MHz

F2 = FRF + 6 MHz, maximum gain

<1 GHz at antenna input

>1 GHz at antenna input

IF_BW = 200 kHz

IF_BW = 200 kHz

Modulation index = 0.875

Desired signal 3 dB above the input sensitivity level,

CW interferer power level increased until BER = 10−3,

image channel excluded

IF filter BW settings = 100 kHz, 150 kHz, 200 kHz

IF filter BW settings = 100 kHz, 150 kHz, 200 kHz

IF filter BW settings = 100 kHz, 150 kHz, 200 kHz

Image at FRF = 400 kHz

Image at FRF = 400 kHz

Swept from 100 MHz to 2 GHz, measured as channel

rejection

Desired signal 3 dB above the input sensitivity level,

CW interferer power level increased until BER = 10−2

FSK mode, BER = 10−3

FRF = 915 MHz, RFIN to GND

FRF = 868 MHz

FRF = 433 MHz

See the RSSI/AGC section

902 MHz to 928 MHz band,

VCO adjust = 0, VCO_BIAS_SETTING = 10

860 MHz to 870 MHz band, VCO adjust = 0

433 MHz, VCO adjust = 0

PA = 0 dBm, VDD = 3.0 V, PFD = 10 MHz,

FRF = 915 MHz, VCO_BIAS_SETTING = 10

1 MHz offset

From 200 Hz to 20 kHz, FRF = 868 MHz

Measured for a 10 MHz frequency step to within

5 ppm accuracy, PFD = 20 MHz, LBW = 50 kHz
