FIELD: radio engineering. SUBSTANCE: frequency synthesizer of phase metering devices has reference generator 1, code-controlled synthesizer 2 of metric frequencies, two channels 3, 4 each including tunable generator 5, first, second and third frequency dividers 6, 12, 13, first and second adders 7, 17, first, second and third band-pass filters 16, 8, 18, phase detector 9, constant current amplifier 10, low-pass filter 11, first and second harmonic generators 14, 15. Synthesizer forms simultaneously two signals with shift in frequency with diminished relative phase fluctuation. EFFECT: enhanced operational stability. 1 dwg
