"That's the latest and greatest 70Ghz technology. 24Ghz has been out for a while. 24Ghz RADAR from Infineon
24Ghz chip is about $7 in single quantity. The $125 part from TI will no doubt come down to less than $10 each once it is in…"
"Another option and perhaps better solution will be the new RADAR chips from TI. Originally intended for automotive use they are releasing an industrial version too. None of the problems associated with LASER ranging. These are uses to detect…"
"GPS uses a radio receiver which operates at about 1.5ghz. As long as no RF blocking material blocks the signal (coming from satellites overhead), the GPS will receive data. RF blocking material; metal or carbon fiber (i.e., electrically conductive…"
Yeah! That's what I was talking about. They use three 24A/190A burst MOSFETS in parallel with a couple of flip-flops set by PWM. Although it is only for 3S, some beefier MOSFETs would fix that.
Additionally, probably some…"
