There are still some places the Internet of Things fears to tread. Researchers at the University of Arkansas and the KTH Royal Institute of Technology, in Sweden, are building a radio for those places. This month, in IEEE Electron Device Lettersthey describe a mixer, a key component of any wireless system, that works just fine from room temperature all the way up to 500 ºC. It’s the first mixer IC capable of handling such extremes.
