I think you were part of the chat with Jo and Berkut on the keypub forums regarding Russian GaN modules. We also talked about on this forums:
Angstrom completed experimental development "siloviki-6A"
By order of OJSC "Concern PVO" Almaz-Antey ", JSC" Angstrom "exercised MF OCD" siloviki-6A ".
R & D was carried out with the aim of developing and mastering mass production of silicon chips intelligent transistor switches in open-frame design for the modulator power amplifier power MRP AFAR X- and P-band based on GaAs and of GaN-transistors:
Silicon modulators keys for power amplifiers in sostave- equipment OJSC "Concern PVO" Almaz-Antey "on the basis of GaAs-transistor;
Silicon modulators keys for power amplifiers in sostave- equipment OJSC "Concern PVO" Almaz-Antey "on the basis of GaN-transistors.
Developed intelligent silicon transistor switches are complete functional units, which include the latest semiconductor switching elements with built-in protection.
Using the developed transistor switches based on this technology as part of the equipment of OJSC "Concern PVO" Almaz-Antey "allows you to:
improve the technological level, reliability and durability of the equipment;
reduce the weight and size parameters at 20-25%;
reduce equipment costs by 20-30%.
Silicon transistor switch used to power modulators, power amplifiers based on GaAs-transistor is a functional analogue of Smart key - BTS640 company Infineon Technologies AS (Germany).
For silicon transistor switch used for power amplifiers modulators power GaN-based transistors, direct domestic and foreign counterparts absent.
As a result of the work we received positive feedback from the OJSC "Concern PVO" Almaz-Antey "- the customer OCD" siloviki-6. "
Thanks I don't really remember the keypubs discussion so can we expect S-500 radar to have GaN module or some other radar ?
Dunno, hard to say. I imagine it is the radar that is really holding back the development of S-500 so far as the project has been ongoing for years. And this is from a couple of years ago. So I assume that they either already have it working or are still working on it. Russia has come really far in its development of GaAS modules and there is word and even evidence of Russian GaN modules but we know even less about them. All we know is that Rostec is really behind its development.
