C1061 The Tr Component Turned out to be a Circuit Board

How can radiation electromagnetic waves, in the beginning, use an antenna, an antenna, a high-frequency signal load up and then launch.2

Later on, the technology improved, and a magnetic control tube appeared. It was a vacuum tube. The electrons inside the tube were controlled by the perpendicular magnetic field and the constant electric field. The magnetic field began to interact with the magnetic field, converting the energy obtained from the constant electric field into microwave energy. And thus achieve the purpose of producing microwave energy.

This device happened to happen in During World War II, and it was completely practical in World War II. All kinds of radars could not be separated from the magnetic control tube. This magnetic control tube had been constantly modified and used until now.

That's right, even now, even if it was the incomparably advanced Flat Gap Radar antenna, it was still just an antenna that emitted electromagnetic waves. The source of the electromagnetic waves was still the magnetic control tube behind the antenna.

Even if it was the passive mutual control radar, it was still the same. The core was the magnetic control tube.

Only when it came to the active Phase Controlling Array radar would there be a change in principle.

The core of the passive phase control radar was a transformer, and behind it was an electromagnetic wave. The Phase Shifter in front changed the position of the electromagnetic waves, while the Active Phase Controlling Radar... The antenna itself releases electromagnetic waves. When it is launched, the phase was different.

Therefore, the proactive phase-control radar was also known as the organic phase-control radar. The antenna would be launched by itself. This was the source.

And the core of the source control radars was the T / R component. Each component was a launch / reception unit. At the same time, this was not an ordinary antenna. It was a circuit board itself.

Qin Guan knew that this component was very important, and he had once exchanged information on this component. He gave it to 114 units, but Qin Guan had never opened it. He was just a super military fan. When it came to this kind of professional knowledge... He knew very little about it.

Now Qin Guan was surprised to find out that this thing was actually a circuit board.

"This component module, the basic setting of the chip includes 3 MMMICS components and 1 digitalized large-scale integration circuit VLSI. The first three are high-power amplifiers, low-noise amplifiers that add protection circuits, amplifiers that can be adjusted, and modulated modules."

After a pause, Worker Zhang continued, "We want to integrate all the circuits into one chip, but we failed. This kind of integration is too difficult, there is a serious electromagnetic interference problem. So we categorized the circuits according to their functions and placed them on different chips. Then connect them through a mixed microcircuit. "

Qin Guan held this component in his hand and was secretly surprised. So that's how it is. The development of our own microelectronics technology can be considered as laying the foundation for the research and development of the control array radar. He had thought that it was some kind of precise processing, but it turned out to be like this.

"We are now using the GAAIS technology based on the GAIS technology. One of its shortcomings is that the heat conductivity is extremely low, so the circuit based on GAIS needs to be deconstructed." Worker Zhang smiled. "Actually, this module is everyone's contribution. My main contribution is its cooling design."

In the past, he only knew that the proactive array radar was very advanced. At the same time, they also knew that the technology was very difficult to achieve. As for how difficult it was, Qin Guan didn't know, but now that he was here, he finally understood. This antenna was a circuit board, and there were four integrated circuits on it. Then, he needed to combine all these small slabs together.

"Because it needs to heat up, we need to install every T / R module on the backboard of the heat dissipation board so that we can release the heat generated by the T / R components in time."

"We are using the most advanced piece structure, each T / R module is formed by three layers of circuit boards stacked vertically. And each layer of circuit board includes four T / R circuits. The heat generated by the circuit in the T / R components is transmitted to the surrounding metal structure through the circuit board. Such a structure had many problems. For example, the biggest problem was that each antenna array radiation unit must accurately ensure its position in the array. The precision requirement is even higher than the gap processing of our Flat Gap Radar."

Qin Guan nodded. He thought of something and said, "This kind of mutual control array's Radar Antenna should have two ways to disperse heat, wind and water, right?"

Qin Guan remembered the Divine Shield ship in Han Country, the flat mutual control array radar. At first, the cover was arc-shaped, and that was to disperse heat and wind. Later on, it became a flat plate. It was the way of the water and cold. Compared to the two, the water would definitely be colder.

"Right, what we need to do now is the Airborne Radar. This kind of radar can only use cold wind to disperse heat. Furthermore, due to the high speed of the fighter aircraft, it would not be a problem for the cooling air to enter. If we want to operate the ship, then the cold water is the right choice. "

Qin Guan's arrival today was indeed an eye-opener. Up until now, they had finally made a breakthrough in their technology on the fourth generation of fighter jets, and that was the control array radar!

Suddenly, Qin Guan thought of something. "Our radar has a higher requirement on the processor, right?"

If every radiation unit needed precise control, then the computer processing ability needed a lot.

"Yes, President Qin, we can only use commercial planes at the moment. We have already taken a fancy to the Han Chip Technology Company's Han Xin Number 2 chip. When this chip is combined, the server that is formed can completely meet our needs. However, this is also one of the reasons why people are criticizing us. They think that we can't avoid electromagnetic radiation in nuclear wars by using commercial opportunities."

Qin Guan nodded and said, "Up until now, there are still people who are holding on to the idea of a nuclear war. If we want to deal with a nuclear war, we can only use electron tubes. If we use an electronic tube, how big would our equipment be? The future war is a high-tech war, nuclear deterrence, it is only a form of deterrence. If a nuclear war really breaks out, then even if we use an electronic tube to develop an alarm machine, that's no use!"

There were sounds of opposition coming from the control array's radar, which also included a large increase in the processing ability required. It must be used for commercial purposes, and not for military reinforcement chips.

Actually, looking at the world, which police aircraft was used for specialized military products? They were all used after the commercial aircraft was reinforced, even if it was an Aegis Warship. It was also used for small-scale commercial aircraft, because the performance of the military was low. If the processing ability was not enough, it would not be able to meet the requirements.

"My personal suggestion, since our proactive phase-controlling radar technology has already developed... We might as well use this technology to build an alarm system. When the Air Force holds the prep technology meeting, I will give my full support. " Qin Guan said, "Let's aim in the direction of the mutual control array's radar!"
