The figure shows the simplest form of NE-602 DCR basic circuit. There are multiple structures of the input parts and local oscillator partial circuits. The figure shows the most common one. Output signal is led from pin 4 or pin 5 and is feedback to the audio amplifier. This circuit can work but not be recommended, because the circuit will be relatively with large noise and image signal and no filtering. Figure: NE-602 Direct conversion receiver partial circuit
