In Britain, moving to a new stage in the development of a new generation of GaN radar for fighter jets

British defense company BAE Systems announces the transition to a new stage in the development of promising radar for fighter jets. This is a new generation of radars, which, as planned, will combine the technology of electronic warfare (EW) and communications.


Representatives of the research laboratory of the aforementioned company report that a semiconductor technology based on gallium nitride (GaN) with a millimeter range for use in new generation radars is being carefully studied and phased.

BAE Systems is promoting millimeter-wave gallium nitride (GaN) semiconductor technology for the implementation of next-generation radar systems - electronic warfare and communications. These GaN radars are planned to be used in promising means. aviation, including fighters, which theoretically belong to the 6th generation of the Air Force.

The combination of GaN used makes it possible to provide a relatively wide spectrum of frequencies with high information transfer efficiency. One of the main advantages that British researchers are talking about is the small size of the transmitting and receiving devices in comparison with those that are in operation today. At the same time, the power of the output signal remains high.

Gallium nitride is said to reduce the cost of creating a high-performance radar.

Chris Rappa, Director of Radar Product Range:

The GaN program provides the basis for the development of advanced technologies that could lead to the emergence of new critical technologies for the next generation of fighter aircraft.

It is noted that such work is carried out both in the interests of Britain and in the interests of the United States "taking into account American technological experience."

Previously, the creation of a new radar based on gallium nitride was announced in the American Raytheon. In this case, the radar is created for advanced air defense systems, which are designed to replace the Patriot air defense system.

      I agree ... we have been using gallium nitride on sapphire for a long time ... I suspect that for the same purpose ... surprisingly, the technology of epitaxial growth of gallium nitride was developed by the group of Zhores Alferov. And in Taiwan, it was these guys who launched the technology. LEDs ...

        35 years ago, physicists from the Institute of Physics and Technology of the Siberian Branch of the Academy of Sciences already dabbled in epitaxial films on gallium arsenide, and what has become so attractive about nitride?

          and than nitride has become so attractive now


          Eeeee - well, in particular - the band gap increased relative to silicon, which provides an increased upper working temperature of the crystal.

          As you know, the conductivity of the "intrinsic" (i.e., completely pure - absolutely no impurities) semiconductor is proportional
          e "in power" (- "band gap" / 2kT)
          - So, its own semiconductor - silicon - becomes almost a "conductor" already at 150 degrees Celsius, and accordingly, the maximum temperature of the crystal - can not be higher than 150 degrees. And given the thermal resistance of the case of a semiconductor device - the maximum temperature of the operating environment of silicon devices - does not exceed 125 degrees.
          - Whereas devices based on gallium nitride - it is quite possible to operate at 200 degrees Celsius. And considering that the heat transfer rate is proportional to the temperature difference between the refrigerator (the external environment of operation of the device) and the heater (semiconductor device) - with the same dimensions of the device and the same operating conditions, the gallium nitride device can dissipate almost twice as much power.

          - for which they fought ...

      And please tell me, dear Aron, what are such "complex" qualities and what is the most promising and most advanced technology that distinguishes AFAR on GaN from AFAR on GaAs?
      Performance? At a price? Manufacturability? Immunity? Heat sink?
      And praise, praise, and for what - it is not clear. laughing

        May I answer?
        Gallium nitride works at higher temperatures than arsenide, and the thermal conductivity of sapphire on which it is grown is quite decent. And in other properties - not inferior. Accordingly, the power of the module can be raised, with the same dimensions. Strong. More than two times.

          Thanks for the info: yes, it’s slightly impressive, but you must admit that this is not a breakthrough.
          How is it with the detection distance? Back to the cube, or is it still the fourth degree of power?

      We lag behind so far and there are no grounds for reverse thoughts, alas.

      We have to seriously invest in electronics, and preferably not even yesterday but the day before yesterday. Today we have the results of investments a decade ago. As the situation in this area does not change, tomorrow the situation will be worse for us than today.

              Yeah, and where is the result? So far, the introduction of AFAR is not even based on GaN technology, but at least on GaAs, there are big problems. Strong dependence on the foreign component base and complete reluctance to develop their own. One example, albeit an indirect one: in the Russian Federation for over 20 years there have been (and probably still are) preferences for foreign manufacturers of aircraft. This led to the half-dead state of our civil aviation manufacturers. Or here is the desire to make SSJ purely in cooperation with foreigners, which led to the current stagnant position of this ship. It’s somehow impossible to push it to EBN, and so it is everywhere, in general everywhere.
              You suggest me to believe that everything is different with GaN technology? Well, I do not. Faith is to fools.

                        There is nothing reliable in open sources on this subject (our AFAR). From the word AT ALL. The information was closed, but now it is even more closed ... Mikran works on GaAs technology, and many others on GaN ... And there are NO and there can be no imported components - this has long been banned for use. A hard replacement was given, but there is no arguing against the instructions. And what do you have against Superjet? 200 have already made them!
                        Not a small park at all. His problems are service, they are being solved, and will be solved soon completely. The French with the engine also drove Brachox on the "hot side" ... Permians rested, corrected ...

                        I have nothing against the Superjet, except for a claim to the approach to its implementation - initially they could put everything in their own way and there would be no problems with the same service, which pretty much hung up including on import. And cooperation with foreigners did not justify itself (IMHO) since the board turned out to be like a child of seven nannies and the project itself was dragged out purely by the efforts of the Sukhoi Design Bureau. The officials of the Russian Federation have some kind of servility to all Westerners, which I personally would have treated with healing shots.

                        As for the production of AFAR, my skepticism will weaken only when AFAR will be massively put on both air defense systems and aircraft. As long as there is a Beetle-A for the MiG-35 which more and more resembles that stewardess and confusion with the Squirrel, since the deadlines for the implementation of the Su-57 program creep to the right all the time and it is not clear from what. An indicator of the affairs in the field of AFAR is also what Indians want to modernize the Su-30 AFAR, while ours only crumple in response, although this market is huge and must be taken at any cost. Yes, the Indians are still ... dancers, I don’t argue, but anyway.

                        And the fact that AFAR is secret does not occur to you? Well, not everything we can “sell” for export! Even what is on our Su-35 and MiG-35 is deeply secret. The plant for the production of AFAR has already been built. So everything is not as bad as it seems. Have you heard a lot in the open press about Vanguards, Zircons and Daggers ...? And avionics - an even more secret thing ...

                        This is rather stupid, because if there was an AFAR, it would be possible to leave a few weaknesses in it, and sell a couple of back-doors to the Indians in export guise - the proceeds would completely cover R&D and other costs and give money for new development.

                        This secrecy demonstrates two things: 1. There can be nothing and no, and the best way to cover up your bare ass is to keep it secret. 2. Even if there is something, then they have the feeling that there is nothing, while for Western intelligence all this secrecy is like a fig leaf in one place. As for the Vanguard, Zircon and Dagger, they obviously are, otherwise they would not have been advertised so eagerly. A dagger is a shallow alteration of Iskander. I believe that Zircon is, but as for AFAR, I doubt it and only my series will dispel my doubts.

      The West is too vague a concept. There are too many of these countries called “west”. And they do not all have the same equal. What technologies do you mean? Are those of them based on Korean chips and assembled at Chinese factories? Or at discoveries in theoretical science, where does Russia contribute? Intel or Maykosoft, are there any Russian developers there? Or Chinese, or Indians?
      Is Brazil quite a west to itself? In all countries there are some peculiarities, for example Obama was surprised by the antiquity of computers in the white house.

    GaN radar does not exist. There is a Multifunction Phased Array Radar - a multifunctional phased array radar. And the introduction of GaN in the manufacture of semiconductor devices instead of LDMOS or Si-Bipolar Transistors can significantly reduce the overall and weight parameters of the equipment and increase the energy characteristics, which is necessary to create a compact MPAR that can be placed on an airplane.
    In the photo modules for a similar purpose. On the right - according to "traditional technologies", on the left - based on GaN.

            In fact, you are wrong, all countries are engaged in the creation of ROFARs, it’s just called everywhere differently and has a different design, but the method is the same. It’s like a helicopter class aircraft that uses the “blade swash” method for its horizontal movement, and the “blade swashplate” itself can have a bunch of different concrete implementations. The ROFAR method has the same method, and it consists in using several channels with different electromagnetic spectra in them, so as to minimize their influence on each other. Well, the complexity of ROFARs lies in the production of sensor blocks consisting of many different materials having different behavior under the same conditions. Actually, because you don’t see “ROFAR-RLS” because the sensor units are created and tested in laboratories and some kind of “full-scale” tests are unnecessary and even harmful for them because, unlike the “test stands”, the test cycles are not identical there.

            Well, if you read and did not understand the text above, then I explain it with an example of a helicopter, in other countries an aircraft using the “blade swash” movement method is called the name of a specific “swashplate”, and not a “helicopter”.

And the cause of the error lies in the fact that the editors of the article are not aircraft engineers and therefore did not understand the difference between blade swashplate и step change device, which I mentioned in a previous post, and both devices are almost identical in appearance, and both of them can be used and not be used by the same convertiplanes (like the same XC-142 doesn’t have either one or the other, although it is a convertiplane), so that the mistake of the editors is excusable ... (already edited the wiki article)

                      Or do you think materials from closed conferences in Sarov or Kurchatnik will be in the public domain?

                      Exactly! all works on this and similar topics relate to closed sections, military, commercial (industrial) or scientific is not so important. And not only and not so much in radar as in electronics, material science, nuclear / molecular physics, etc. Yes, even that which is not a secret is still not shared. For example, who needs diagrams of the mutual influence of the five parameters in the form of a book with rows of numbers? What if a book weighing a couple of tons? or excel table in hundreds of megabytes? or * .txt in thousands of megabytes, or even gigabytes?
                      Well, you can bring this into simple articles, but which of the experts and even amateur fans need simple stories about the fact that the "sun is yellow" when it is scientifically proven that this is a lie, even if it is believed by ordinary people who look at the yellow sun every day? (Not Well, the truth is, after all, many believe that it is yellow, and you start to prove the opposite will be written down in psychos or "very smart, yes ?!" or someone worse) ...

            China just does too. Someone did not see, and someone saw, at least the layout.

        As soon as these radars shine on the output power, they will be like a Christmas tree. Our approach towards ROFAR seems more promising.

        Generally you are right .. hi

    the supply of material is horrifying ... gallium nitiride radars. in Russian it should sound - the use of materials of microelectronics on a gallium nitride base. the substrate. on which microchips with specified characteristics will be received.

      And with what Makar these radars are dangerous for us - the fact that they will be expensive in production is, of course, in Russia the same do not stand still in the development of radars.

    The development of LNA, phase inverters, logic based on gallium arsenide in the USSR was engaged in as early as the 80s.
    And certain successes were achieved.
    The carrier velocity in gallium arsenide is an order of magnitude higher than the carrier velocity in silicon. And this means that the speed of logical and high-frequency circuits is ten times higher.
    All these developments and developments were ...., like the Soviet Union.
    Instead of developing electronics and its individual areas in Russia, they chose to "cut" the budget in Skolkovo ...
