Fig. 4 - The two common diode balanced-modulator circuits are (A) the bridge and (B) the ring. Condensers C 1, C 2, C 3 and C 4 are r.f. by-pass condensers, used to complete r.f. paths without short-circuiting the audio. Fig. 5 - A modulating signal as in (A) gives an r.f. output from a balanced modulator as in (B).

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 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.

Therefore, a balanced modulator may be defined as a circuit in which two non-linear devices are connected in a balanced mode to produce a DSB-SC signal . In this article, we shall discuss a balanced modulator circuit using diodes . Fig.1 shows the balanced modulator using diodes as non-linear device . Fig 1

Circuit Diagram Of 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).

Balanced Modulator FET circuit Suppression of Carrier DSBSC

General Description The LM1596/LM1496 are doubled balanced modulator-de- modulators which produce an output voltage proportional to the product of an input (signal) voltage and a switching (car- rier) signal.

Balanced Modulators

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.
