The architecture of a frequency synthesizer with a parasitic frequency modulation auto compensation channel and a broadband parasitic phase modulation autocompensation channel is presented. The results of modeling the frequency compensation characteristics of the presented architecture when changing node parameters are analyzed.
Analytical expressions are obtained for the transient characteristics of the parasitic angular modulation (PАM) autocompensation channels of frequency synthesizers (FS) and partial dynamic characteristics are calculated. The dynamic characteristics of the PАM compensation channels were evaluated when the parameters of the MF nodes for aviation radio communications were changed
The needs determining the directions of development of on-board radio communication systems are considered. Architectures of frequency synthesizers with two-point frequency modulation and channels of auto-compensation of interference of a pulse-phase modulator are given.
