A multifunctional frequency synthesizer with a low level of frequency and amplitude fluctuations, designed to work in airborne radar stations, to form a frequency grid of output signals in the 3 cm range and a grid of heterodyne frequencies corresponding to each frequency of the output signal, as well as the frequency of the second local oscillator and reference frequencies (synchronization frequencies).
