Sub-1GHz RF solution offers low-cost connectivity

The devices are based on TI's sub-1GHz CC1101 RF technology. They are pin-, register- and code-compatible, as well as backwards compatible with existing sub-1GHz systems.

According to TI, the CC11xLDK-868-915 and CC11xLEMK-433 development kits provide complete hardware performance testing and software development platforms for the product family. The kits also offer low-cost reference designs, with a compact PCB antenna for 433, 868, 915MHz, featuring a reduced component count and complete design ready for FCC and ETSI certification. The small-size, compact PCB helix antenna represents only a quarter of the size of previous PCB antennas, and is useful for applications requiring high antenna efficiency in a compact area.

The sub-1GHz RF Value Line family offer seamless integration with CC1190 range extender and gives up to 27dBm output power and -120dBm sensitivity, and up to 20dBm output power without frequency hopping (FHSS) under FCC. It is compatible with CC1190 range extender, MSP430 Value Line microcontroller, and TPS62730 step-down converter with bypass mode for ultra low power wireless applications.

The solution is packaged in a ROHS-compliant, 4 x 4mm QFN-32. Pricing starts at $0.75 in 1,000-unit quantities.

The CC11xLDK-868-915 development kit is available for $299. An additional CC11xLEMK-433 development kit is available for $99.
