IF Amplifier Functional Diagram IF Dec1 39 IF In 38 IF Dec2 40 IF Out 41 Σ RSSI Pin Symbol/Type Description Description 43 VCC See Figure 5. VCC, Positive Supply Voltage 44 Lim In Limiting Amplifier Input Limiting amplifier input source impedance is 330 Ω. This amplifier has 84 dB of gain with 3.0 dB bandwidth of 40 MHz; this enables the IF and limiting ampliers chain to hard limit on noise. 45, 46 Lim Dec1, Lim Dec2 If Decoupling These pins are decoupled to VCC to provide stable operation of the 2nd IF limiting amplifier. 7 RSSI RSSI The RSSI circuitry in the 2nd, 3rd, & 4th amplifier stages outputs a current when the output of the previous stage enters limiting. The net result is a RSSI current which represents the logarithm of the IF input voltage. An external resistor to ground is used to provide a voltage output. Figure 5.
