CC1190 RF range extender

Texas Instruments Inc. is rolling out a highly-integrated, cost-effective RF range extender for low-power wireless applications at 850MHz to 950MHz, such as wireless sensor networks, automatic meter reading, and wireless industrial controls, consumer and audio systems.

The single-chip CC1190 integrates a power amplifier (PA), a LNA, switches and RF matching, which eliminates expensive discrete components, simplifies design layout, reduces test time, improves RF performance and shrinks overall board space.

The CC1190 works with TI's CC1101 sub-1GHz transceiver and the CC430 or CC1110 SoC. The CC1190+CC1101 solution can provide up to +149dB link budget. Customers that need to extend the range of their existing industrial sensors or utility energy meters will be able to eliminate repeaters or routers, reducing overall system costs.

The CC1190 increases link budget by providing a PA for increased output power, and an LNA with low noise figure for improved receiver sensitivity. The integration of PA, LNA, switches and RF matching reduces product design cycle.

The RF range extender features up to 27dBm (0.5W) output power and 6dB typical sensitivity improvement with CC11xx and CC430.

The CC1190 is available in a ROHS-compliant, 4mm x 4mm QFN-16 package. Suggested resale pricing starts at $2.10 in 1,000-piece quantities.
