The output of a reference frequency generator is connected to the input of a high-order frequency multiplier, the output of which is connected to the input of an additional frequency multiplier and to a first input of a frequency converter. The output of the additional frequency multiplier is connected to the input of a frequency divider, the output of which is connected to a reference input of a frequency-phase detector. The output of the frequency converter is connected to the input of a frequency divider with a variable division ratio, the output of which is connected to another input of the frequency-phase detector. The output of the frequency-phase detector is connected to an error signal filter, the output of which is connected to the input of a controlled generator. A second input of the frequency converter is connected to the output of the controlled generator. The main technical result is an increase in the frequency resolution and spectral purity of an output signal.
A frequency synthesizer, including the reference generator, whose output is connected to the frequency multiplier, the frequency converter, frequency divider, whose output is connected to the input of the frequency phase detector, whose output is connected to the input of the error signal filter, whose output is connected to the input of the controlled generator, distinguished by the fact that the input of the frequency multiplier is connected to the input of the additional frequency multiplier, whose output is connected to the input of the frequency divider, whose output is connected to the reference input of the frequency phase detector, while the frequencies of the controlled generator and the reference generator are related by the following formula
