ring amplitude modulation circuit

The diode ring amplitude modulation circuit consists of four diodes forming a loop
, so it is called a diode ring amplitude modulation circuit. Diode ring amplitude modulation
circuits have greater advantages.
    Due to the discreteness of diode characteristics and circuit reasons,
resistive elements are often used to correct the circuit. In the actual ring amplitude modulation circuit as shown in the figure,
    the diode VD is 2AP9. Reference values ​​for other component parameters:
resistance; Ri =R2 =Ra =R4 -lOOtl,RRPI -Rr{PZ—470fl.
    The diode ring amplitude modulation circuit transforms the low-frequency modulation signal and the high-frequency carrier
signal through the circuit into a high-frequency amplitude modulation signal and outputs it. The amplitude modulation circuit
has a simple structure, few output harmonics, good symmetry and balance, and is often in
the form of integrated circuits.
