A careful look at RF for your IoT PCBs
IoT devices remain in their infancy, with a lot of questions being asked and experimenting going on. Radio frequency, or RF, is one technology that IoT companies and startups are dialing into to advance state-of-the-art IoT and, in doing so, increasing profit margins for their IoT products. In some cases, there are a lot of guesstimations going on, largely based on assumptions gleaned from smartphone technology.
However, with IoT devices and unlike smartphones, RF is a brand new ballgame, something akin to “black magic” as some tech pundits put it.
The prudent thing to do is take a close look at RF and the specific challenges it poses to IoT devices. There are some key design considerations you have to factor in. Those deal with the right RF antenna to use, anticipated RF interference, impedance matching and testing.
