Function

Demodulator tank circuit connection IF 1

(high impedance input – slope of S-curve can be determined by external resistor

between pins 1 and 2)

GND

AF output IF 1 (emitter follower)

AF output IF 2 (emitter follower)

Supply voltage

Demodulator tank circuit connection IF 2

(high impedance input – slope of S-curve can be determined by external resistor

between pins 1 and 2)

Operating point feedback of limiter amplifier and low end IF 2

(RF decoupling of IF amplifiers with appropriate capacitors is required!

Operating point feedback of limiter amplifier IF 2

(RF decoupling of IF amplifiers with appropriate capacitors is required!)

IF 2 input

(input of limiter amplifier IF 2; internal resistor between pins 9 and 11 is typ. 800 Ω)

GND

Internal reference voltage (typ. 6 V)

IF 1 input

(input of limiter amplifier IF 2; internal resistor between pins 14 and 15 is

typ. 800 Ω)

Operating feedback of limiter amplifier IF 1

(RF decoupling of IF amplifiers with appropriate capacitors is required!)

Operating point feedback of limiter amplifier and low end IF 1

(RF decoupling of IF amplifiers with appropriate capacitors is required!)
