RSSI Output
The RSSI value can be read as a 6-bit word in the Status register. Its value is given in dB and is linear as
shown in
Figure 4-14. Typical RSSI Output (Board Implementation, T = 25°C, V
Note:
The RSSI’s dynamic range is 50 dB from a -95 dBm to -45 dBm RF input signal power, over temperature
and power supply ranges. The value of the RSSI’s LSB weighs approximately 1.3 dB in the linear area.
The RSSI value is measured from the IF2 chain.
As the successive approximation ADC is shared by the RSSI, V
surements, some bits of the CTRL1 register must be selected for a correct measurement, as illustrated
in
Figure
Should the RSSI be required for accurate measurement purposes (for precision above
5 dB), then one value should be measured with a calibrated RF source and stored into the microcontroller
during production testing.
