N516BS-B Ultra-Long Range Sub-1GHz RF Transceiver Module
Engineered for Maximum Reach and Reliability in Demanding IoT Applications
Product Overview
The N516BS-B is a professional-grade, high-performance RF transceiver module engineered for ultra-long-range communication in the global 868MHz and 915MHz ISM bands. By integrating Texas Instruments' flagship CC1125 transceiver and the CC1190 range extender front-end, coupled with a high-stability TCXO, this module delivers an unparalleled combination of +27dBm output power and -126dBm receiver sensitivity. It is the optimal solution for developers requiring robust, reliable, and extended-range connectivity for Industrial IoT (IIoT), smart city infrastructure, and remote telemetry applications.
Key Features & Benefits
Industry-Leading Link Budget: The powerful combination of +27dBm transmit power and -126dBm receive sensitivity enables reliable communication at >10 km Line-of-Sight ranges.
High-Performance RF Core: Based on the proven Texas Instruments CC1125 narrowband transceiver and CC1190 Power Amplifier / Low Noise Amplifier front-end.
Superior Frequency Stability: Integrated TCXO (Temperature Compensated Crystal Oscillator) ensures stable frequency performance across a wide temperature range (-40°C to +85°C), critical for narrowband operation.
Global Frequency Compliance: Available in N516BS-B-868M (860-880MHz) and N516BS-B-915M (910-960MHz) variants, perfectly aligned with EU and North American license-free band regulations.
Flexible Integration: Supports both Surface-Mount (SMD) and Plug-in (Through-Hole) installation methods, streamlining prototyping and volume production.
Low Power Operation: Receive mode current of only 35mA, combined with the CC1125's advanced low-power sleep modes, makes it suitable for battery-powered devices.
Complete Development Support: Accelerate your time-to-market with available reference designs, driver libraries, and configuration tools.
