The MC1496 is a monolithic transistor array arranged as a balanced modulator-demodulator. The device takes advantage of the excellent matching qualities of monolithic devices to provide superior carrier and signal rejection. Carrier suppressions of 50dB at 10MHz are typical with no external balancing networks required.
Balanced Modulators
Balanced Modulation. Ring or Balanced Modulation is technically known as four-quadrant modulation as it always produces sound, regardless of whether the modulator or the carrier are negative or positive. In addition to the two quadrants described above for amplitude modulation, when the modulator is negative, the positive and negative.
D.S.B. balanced modulator
Modulators (sometimes called balanced-modulators, doubly-balanced modulators or even on occasions high level mixers) can be viewed as sign-changers. The two inputs, X and Y, generate an output W, which is simply one of these inputs (say, Y) multiplied by just the sign of the other (say, X), that is W = Ysign(X).

In electronic communications, a balanced modulator is a circuit that produces double-sideband suppressed-carrier (DSBSC) signals: It suppresses the radio frequency carrier thus leaving the sum and difference frequencies at the output. The output waveform lacks the carrier, but still contains all the information a traditional AM signal has.

Excellent gain and carrier suppression can be obtained with this balanced modulator circuit by operating the upper (carrier) differential amplifiers at a saturated level and the lower differential amplifier in a linear mode. The recommended input signal levels are 60 mV rms for the carrier and 300 mV rms for the maximum modulating signal levels.

A Balanced Modulator Circuit is a type of modulator that produces an output signal that is the product of two input signals- the message signal and the carrier signal. Balanced Modulator Circuit consists of two or more active devices circuit arranged in a balanced fashion so as to suppress the carrier signal.

Balanced modulator consists of two identical AM modulators. These two modulators are arranged in a balanced configuration in order to suppress the carrier signal. Hence, it is called as Balanced modulator. The same carrier signal c(t) = Ac cos(2πfct) c ( t) = A c cos ( 2 π f c t) is applied as one of the inputs to these two AM modulators.
