Description

one

The invention relates to engineering and may be used to make electrical oscillations in phase.

However, from the known devices for manipulating the RF generator, there is a "press and release" frequency generator, a frequency divider and a manipulation unit, the output of the frequency generator "pressing through the phase shifter, and the output of the frequency generator" pressing out the transmitter to the balanced mixer inputs, output. which is connected to the input of the divider hour; totah.

However, the known device does not allow it to be used in systems for which increased phase shifts are necessary, since during manipulation there is a 1 phase shift both in the direction of increase and decrease in the phase of the carrier oscillation.

By OiCHOBHOMy auth. St. No. 144872 and a local device for manipulating an RF generator, containing a phase manipulator connected to a source of oscillation carriers, an AND element with a selector pulse generator, interconnected by a feedback circuit, a control converter, and a single-pulse and trigger B0 0 setting control signals 2 .

However, the known device has a narrow range of phase change.

The purpose of the invention is to expand the range of the phase change of the device for manipulating the RF generator.

For this, in a device for manipulating an RF generator according to the author. St. No. 144872, the output of the phase switch is connected to the inputs of the input key and the element NOT, the output of which is connected via a key to the pulse shaper.

The drawing is a structural diagram of the proposed device.

The device contains a phase manipulator 1 connected to a source 2 of carrier oscillations, an element 3 and a generator 4 selector pulses interconnected by a feedback circuit 5, and a converter 6 of control I1 impulses, a trigger 7 for restoring control pulses, a key 8 , item 9 and shaper 10

pulses. The output of the manipulator 1 is connected to the inputs of the key 8 and the element HE 9, the output of which is connected via a key to the driver 10 pulses. The device. Works the following 0: Bras.

The oscillations of the source 2 are fed to the mainsulator 1, the output ic of which the signal goes to the output of the device and through the element NOT 9 or mine it to the driver 10, the output of which is connected to one of the inputs

element 3. The converter of 6 pulses converts the rectangular information pulses into short negative, corresponding to each positive and negative voltage drop at the input. Negative pulses impulse a generator of 4 selector pulses and, m1 pulses, from its output, pulses arrive at another input of an I 3 element, for which a trigger is used. In case of yoipadbnii in time of pulses at the neipBOM and the second inputs of the element And 3 at the output of the latter, there is a negative impulse that triggers trigger 7, which activates the information boards. When a negative impulse appears at the output of the 3-element. A selective impulse of the generator 4pAHI | T1C through the feedback circuit 5, as a result of which the generator 4 (goes over IB and other steady state. IpHtrrepOiM 7 informational synergies They are phase shift 1.
