The above picture is a multiplication detector circuit. The circuit is single side band amplitude-modulated signal detection. Its demodulation principle is to complete demodulation by multiplying the received SSB Signal and transmitting carrier wave which is recovered by the receiving end. Integrated module MC1496 in the picture is a balanced modulator and demodulator, and the output voltage of the circuit is the product of input voltage signal and switch function. When the circuit works in an intermediate frequency of 9MHz, the sensitivity is 3μV, and the dynamic range is 90dB.
