See TONS of these on AliExpress... What exactly are they? They definitely smell of "anti-drone jammer" type things to me... https://www.aliexpress.com/item/1005010359595614.html

@ret Based on the image, LoRa is a long range RF protocol. GaN is a high power transistor used in RF applications. It might be something as simple as a high power RF front end. Though LoRa in this case might not be the protocol and just be "long range" as in high power.

@l_b_i I thought that, but if you look there's no "in" port so it can't just be an amplifier. There's also not enough in there in terms of micros, RF frontends, etc for it to have much "smarts" in it. I'm 95% sure they are just jammers.

@ret RF I thought front ends don't usually have smarts, just power and frequency management. A jammer would also need some smarts that are not present. If it were just blasting out noise you wouldn't need to worry about any return path, but it looks like there is one there.
