Instruction Manual
Pin.13 “RSSI” Output
In fig.2 it is reported grafically the behaviour of the voltage at the RSSI output in function of the
power of the input signal, in High Gain mode (pin 11 at logic level 0). In fig 3 it is shown the
equivalent diagram but in Low Gain mode (pin 11 at logic level 1).
Both the diagrams have been obtained experimentally applying at the RF input (pin 3) of the
receiver a square wave AM-modulated, with a modulation index of 99%, drawn directly from a
signal generator, and connecting a 10uF capacitor between the pin 11 and GND .
