In this paper, a high-frequency broadband harmonic crossover with feedback modulator is studied. Analyzed the mechanism that forms the effective component of the frequency of separation in the input voltage of the frequency selective amplifier. The influence of the phase shift angle φ of the feedback control signal and the symmetry parameter τ / T of the shunt modulator on the operation of the frequency divider is studied. The relationship between the parameter τ / T and the product of n (frequency division number) and φ is directly proportional. The effects of the optimal τ / T and φ values and the other main loop parameters on the frequency division synchronization bandwidth are pointed out, and the practical applications of the linear approximation theory and the dynamic conduction coefficient method . Taking the high-frequency broadband harmonic divider with 6: 1 frequency division ratio as an example, the general calculation and experimental methods of such divider are pointed out. The designed 6: 1 harmonic divider divides the synchronous frequency band by 14% within the range of satisfactory divider characteristics.
