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 with the CC1190 range extender front-end and 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 systems.
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 PA/LNA front-end for superior RF performance.
Superior Frequency Stability
An integrated TCXO ensures stable frequency performance across the full -40°C to +85°C industrial temperature range—critical for narrowband operation.
Global Frequency Compliance
Available in variants perfectly aligned with EU (868MHz) and North American (915MHz) license-free band regulations.
Flexible Integration
Supports both Surface-Mount (SMD) and Through-Hole installation methods, streamlining prototyping and volume production.
Low Power Operation
With 35mA receive current and advanced sleep modes (<1 µA), it is well-suited for battery-powered field devices.
Complete Development Support
Accelerate your time-to-market with available reference designs, driver libraries, and configuration tools.
