TI's new sub-1 GHz RF family brings more robust, reliable wireless connectivity

DALLAS, USA: Texas Instruments Inc. (TI) has introduced the sub-1 GHz RF performance line family, providing unmatched connectivity for low-power wireless applications in security, smart grid, industrial, wireless healthcare, home and building automation, and other spaces.

The sub-1 GHz RF performance line family meets the market's most stringent RF requirements and provides an industry-leading ability to filter out other RF sources. For developers and consumers, this translates into end products with robust and reliable wireless links that are resistant to disturbances from other wireless systems in a device's surroundings. The sub-1 GHz RF performance line family today consists of the CC1120 and CC1121 transceivers and CC1175 transmitter.

The sub-1 GHz RF performance line can be more than 30 times closer in proximity to other RF systems and potential connection "interferers" than competitive offerings, allowing streamlined coexistence between various connected devices in one environment. With 65-dB adjacent channel rejection at 12.5-KHz offset and 90-dB blocking, TI delivers the industry's most reliable sub-1 GHz connections.

With a 139-dB link budget, the products' range reaches well beyond 10 km and provides maximum indoor penetration. Advanced RF sniff mode also allows systems to listen for RF packets using very low power consumption, with less than 3mA in receive (Rx) sniff mode, while maintaining full RF performance.

"The sub-1 GHz RF performance line is a key enabler of long-range, low-power wireless connectivity that provides uninterrupted, reliable user experiences regardless of the other wireless devices in the environment," said Erling Simensen, product marketing manager, LPRF, TI.

"Consider the fact that one household can contain more than ten wirelessly connected devices in the same space -- from family members' smartphones and health monitors to the home's smart meter, alarm system and more. Frequency is a limited resource, and these devices must communicate on the same bands while filtering out other RF traffic. Our sub-1 GHz RF performance line achieves this, and maximizes RF robustness for the best user experience."
