Wild. I recall back in the early 2000's my dad was working at ITT Gilfilan (I think they are defunct now - https://en.wikipedia.org/wiki/ITT-Gilfillan https://en.wikipedia.org/wiki/ITT-Gilfillan) and the latest hotness was Gallium Arsenide radar technology. Pretty quickly it seems we leveled up to Gallium Nitride.
- preisschild 2y agoYeah the latest and greatest radars (Raytheon AN/SPY-6) is using GaN instead of GaAs (like the older AN/SPY-1 did) too Really cool stuff
- kjs3 2y agoI always remember GaAs as the tech most responsible for killing the Cray-3/Cray-4.
- venusenvy47 2y agoGaN was already becoming popular in the early 2000's for high power RF amplifiers because they operate at higher supply voltages than GaAs. Cree (now Wolfspeed) and Nitronex were big names in GaN back then, with RFMD and TriQuint joining in soon after.
