FREQUENCY SYNTHESISER WITH SWITCHED FREQUENCY REDUCTION CHANNELS Russian patent published in 2014 - IPC H03L7/00 H03L7/16

Abstract RU 2517424 C1

FIELD: radio engineering, communication.

SUBSTANCE: device includes two frequency-phase detectors (1 and 9), two low-pass filters (2 and 10), a voltage-controlled generator (3), a power splitter (4), a frequency divider (5), a low-frequency switch (6), a mixer (7), a reference frequency generator (8) and a control unit (12).

EFFECT: reduced level of phase noise in the output signal, frequency tuning time and level of parasitic spectral components.
