The harmonic generator has the differential type. Through the output transformer, the two rectangular pulses, which have half circle difference, are coupled by the symmetrical differential amplifier circuit. Thus the harmonic generator circuit can be achieved. It is simple, and easy to maintenance. It also has the low cost and saves the characteristics of symmetrical pulse. The performance can be closed to the magnetic saturation type. The 4 kHz harmonic generator is as shown in the picture. Its generating frequency is mainly controlled by the main oscillator. Odd and even harmonics can be used for the presetting, access and road base of the communication machine, and it also can be used for the carrier frequency and pilot frequency of the modulation.
