SUPPRESSED_CARRIER_AM
Double-balanced modulator using Signetics 511 transistor array gives output consisting of sum and difference frequencies of carrier and modulation inputs along with related harmonics. Circuit is self-balancing, eliminating need for pots, Output includes small amounts of carrier and modulating signal. Capacitor between emitters of Q3 and Q6 is selected to have low reactance at lowest modulating frequency.- Signetics Analog Data Manual, Signetics, Sunnyvale, CA, 1977, p 750-751.
