RX Received Signal Strength Indicator (RSSI)

The BiM1 wide range RSSI which measures the strength of an incoming signal over a range of 60dB or

more. This allows assessment of link quality and available margin and is useful when performing range

tests.

The output on pin 11 of the module has a standing DC bias of up to 0.5V with no signal, rising to 2.4V

at maximum indication.

Output impedance is 56k

Ω. Pin 11 can drive a 100µA meter directly, for simple monitoring.

Typical RSSI characteristic is as shown below:
