AM circuit ring

AM diode ring circuit consists of four diodes to form a ring road, so called diode ring modulator circuit. AM diode ring circuits greater advantages. Due to the characteristics of the diode and discrete circuits, etc., often have to use resistive element correction circuit, the circuit shown
AM circuit ring - schematic

in actual annular AM diode VD are 2AP9. Other device parameters reference values: resistance; Ri = R2 = Ra = R4 -l OOtl, RRPI -Rr {PZ-470fl. Diode ring circuit low-frequency modulation signal amplitude and high frequency carrier signal by the high-frequency amplitude modulation circuit converting the signal output Qi. The amplitude modulation circuit is simple structure, less harmonic output, good balance and symmetry, often used in the form of an integrated circuit.
