The F-22's APG-77 phased array radar became cheaper when one key component became a commercial off the shelf part for wifi routers.
- teleforce 3y agoI'm curious, can you share the name of that particular key component?
- carabiner 3y agoNo idea unfortunately. I think I read this a long time ago possibly from a Bill Sweetman report.
- teleforce 3y agoThanks for the clue, apparently it's the GaAs MMIC technology according to the ChatGPT-4 [1]. I've should have figured it out in the first place due to my previous research work of Gallium Nitride (GaN) technology that now become the successor to GaAs technology due to high power Radar requirements. I suppose this is where ChatGPT become really handy for research, as Google is extremely useful for search. Similarly with LIDAR, the autonomous vehicles demand has made the LIDAR sensor now become very affordable for the masses. [1] ChatGPT-4 response: "The key component of the F-22's APG-77 phased array radar that was made cheaper by Wi-Fi technologies, according to Bill Sweetman's reports, is the Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit (MMIC) technology. This technology was significantly reduced in cost due to its widespread use in commercial Wi-Fi systems, allowing the defense industry to leverage economies of scale and reduce the overall cost of producing the radar system for the F-22 Raptor."
- carabiner 3y agoHoly shit that's insane.
- teleforce 3y agoI concur, initially I've tried to search using Google but to no avail. Then I prompted ChatGPT-4 and voila the answers [1]. [1] Prompt: "What is the key component of F-22's APG-77 phased array radar that made cheaper by wifi according sweetman report"
