FIELD: radio engineering.
SUBSTANCE: device includes voltage-controlled generator (1), frequency divider with variable division coefficient (2), frequency-phase detector (3), reference generator (4), frequency divider with fixed division coefficient (5), unit of switched charge pumping (6), unit for determining phase synchronism (7), microcontroller (9), unit for determining synchronism as to frequency (10) and low pass filter (8) which includes two capacitors (8.1, 8.2), two resistors (8.3, 8.4) and two switching devices (8.5, 8.6).
EFFECT: adaptive stabilisation of transfer characteristic of ring of frequency-phase automatic control of frequency synthesiser, which allows optimising it as per the specified quality of dynamic and spectrum characteristics.
