SU382224A1 - ULTRA-HIGH-FREQUENCY DELAY DEVICE - Google Patents

Description

one

The invention relates to the field of microwave technology and can be used in radio engineering microwave devices, which require the creation of a delay (in time) of microwave pulse signals.

A device for delaying a superhigh-frequency signal is known, which contains a radiation device on a ferrite chip placed in a resonator.

The known device does not allow to create large delays of microwave emulsions, which can be varied over a wide range.

In order to increase the delay time, to achieve the possibility of a smoothly regulated delay time and to increase the delay of the selective signals, as well as to change the delay time over a wide range, the proposed delay device further comprises a receiver, a driver for starting pulses, a pump generator and a delay line, the output of the delay line being connected to the device input reradiation, and the input of the delay device through the serially connected receiver, the trigger driver and the pump generator are connected to the control, named by the input of the transfer device.

In the drawing, the proposed delay device.

delays connected to the reradiation device 2. The pumping is carried out with a chain that consists of the generator 3 of the pulse generator 4 n of the generator of the pump J.

The impulse that is required to be delayed is fed to the input of the device. This linkage splits into two points: the delay is delayed in the first place, and the second serves to start the pump from non-radiation. The part of the original signal, which enters the second circuit, is amplified and detected by receiver 3, as a result of which there is an out-pulse, j) st PLYuNII on the pump generator 5 loops. Imnulis pumped from the generator nost on the element 2 of the device, in the last one, it is known non-radiation.

The reradiation occurs in an irradiated crystal consisting of a ferrite garnet melted in a microwave resonator. The resonator is tuned to frequency. which is twice the frequency of the signal, but the tuning signal to the input ycTpoiiCTBa. If the source is at the same time as it gets into the pulse of the pump, then a cestase occurs, i.e., a strong not;) impulse at the frequency of the original signal. In this case, the gain of the non-oscillating pulse at the frequency of the original signal. reach 20-

60 dB in power. The delay time of the re-radiated pulse can be adjusted by measuring the pump power. If this condition is not fulfilled, re-radiation may be absent. To match the time of the signal input to the input device with an activated and 1 pumping pulse interval, the overall delay line and the pump start system, n 1, are used, and from the blocks including receiver 3, the driver 4 and the generator 5.

Thus, the initial pulse is delayed by an auxiliary delay line /. Then the pulse enters the device 2, in which the screech is triggered by re-radiation, from where, after a delay, the output of the device is amplified. At the same time, the initial impulse arrives at the receiver 3, from where, after amplification and detection, it arrives at the starting circuit of the pump generator 5. The latter is started. The pump pulse starts at the instant of time to and ends at the instant of time /. Some delay

in time between the input pulse and the front edge of the pump pulse, due to the response time of the pump start system.
