Source: TITexas Instruments (TI) has introduced a new portfolio of millimeter wave (mmWave) single-chip complementary metal-oxide-semiconductors (CMOS) for precision and intelligence across a wide range of applications such as automotive, factory, building automation and medical markets.

The new portfolio includes five solutions across two families of 76- to 81-gigahertz sensors. TI claims the chips deliver up to three times more accurate sensing than current mmWave solutions on the market. The integrated circuits include a digital signal processor (DSP) and microcontroller allowing designers to implement intelligent and contactless sensing in their systems.

Each of the five chips deliver accurate stand-alone sensing with less than 4-centimeter range resolution, range accuracy down to less than 50 micrometers and range up to 300 meters. TI says the devices consume less power and board space by 50 percent, bring multi modal functionality to avoid false positives and can sense through plastic, dry wall, clothing, glass and other materials, as well as through environmental conditions such as lighting, rain, dust, fog or frost.

The chips are sampling now.
