Изобретение относитс  к радиотехнике.The invention relates to radio engineering.

Известно устройство синхронизации генераторов , содержащее опорный генератор и подключенный к его выходу смеситель.A device for synchronizing generators is known, which contains a reference generator and a mixer connected to its output.

Однако известное устройство имеет большую расстройку частот между сигналом на выходе смесител  и сигналом синхронизируемого Генератора, следствием чего  вл етс  узка  полоса синхронизации.However, the known device has a large frequency offset between the signal at the output of the mixer and the signal of the synchronized generator, resulting in a narrow synchronization band.

Цель изобретени  - расширение полосы синхронизации.The purpose of the invention is to expand the synchronization band.

В лредлагаемом устройстве выход смесител  подключаетс  :ко входу синхронизируемого генератора через делитель частоты.In the proposed device, the mixer output is connected: to the input of the synchronized generator through a frequency divider.

На чертеже представлена функциональна  схема устройства.The drawing shows the functional diagram of the device.

Выход опорного генератора 4, формирующего сигнал с номинальной частотой, подключен к смесителю 2. Второй вход смесител  соедин ют с синхронизируемым генератором 3. Выход смесител  подключен к делителю частоты 4, который соедин ют с синхронизируемым генератором.The output of the reference generator 4, which generates a signal with a nominal frequency, is connected to mixer 2. The second input of the mixer is connected to the synchronized generator 3. The output of the mixer is connected to frequency divider 4, which is connected to the synchronized generator.

Устройство работает следующим образом.The device works as follows.

Сигналы двух генераторО;В преобразуютс  в смесителе 2, и на его выходе, благодар  частотному фильтру, по вл етс  сигнал с частотой, равной сумме частот входных сигналов . Этот сигнал делитс  делителем частоты 4 с тем, чтобы он стал близок по частоте к сигналу синхронизируемого генератора 3. Полученным сигналом выполн етс  синхронизаци .The signals of the two oscillators; O are converted in mixer 2, and at its output, due to the frequency filter, a signal appears at a frequency equal to the sum of the frequencies of the input signals. This signal is divided by frequency divider 4 so that it becomes close in frequency to the signal of synchronized generator 3. The received signal is being synchronized.

Благодар  делению частоты сигнала смесител  2 расстройка частот между сигналом на выходе делител  4 и сигналом синхронизируемого генератора 3 уменьшаетс , что приводит к расширению полосы синхронизации .By dividing the frequency of the signal of the mixer 2, the frequency detuning between the signal at the output of divider 4 and the signal of synchronized generator 3 is reduced, which leads to the expansion of the synchronization band.

Предмет изобретени Subject invention

Устройство синхронизации генераторов, содержащее онорный генератор и подключенный к его выходу смеситель, отличающеес  тем, что, с целью расширени  полосы синхронизации, выход смесител  подключаетс  ко входу синхронизируемого генератора через делитель частоты.A generator synchronization device containing an on-generator generator and a mixer connected to its output, characterized in that, in order to expand the synchronization band, the mixer output is connected to the input of the synchronized generator through a frequency divider.
