Keyword: «auto compensation»

The features of the construction of frequency synthesizers (FS) for radio transmitting devices of on-board communication complexes, the need to compensate for parasitic frequency and phase modulation when using indirect methods for the formation of frequency-modulated signals are considered. The architectures of FS with devices for auto-compensation of pulse-phase modulator interference in the reference channel of the pulse-phase auto-tuning system (PLL), as well as in the feedback circuit of the PLL ring, are given.
