Common diode balanced modulator circuit is shown. It consists of two identical performance diodes and a center-tapped transformer T composition. Diodes VD1, VD2 are 2AP9. Other
elements parameters Parameter test value as shown in FIG. 21-37. Diode function is to balance the amplitude modulation circuit low-frequency modulation signal and high-frequency carrier signal through the circuit into a high-amplitude modulated signal output. The amplitude modulation circuit is simple structure, less harmonic output, is a common amplitude modulation circuit.
