N517AS-B: Long-Range 868M/915Mhz Narrowband FSK Transceiver Module
Overview
The N517AS-B is a high-performance, long-range 868M/915Mhz narrowband FSK transceiver module based on the Texas Instruments CC1120 RF transceiver, integrated with a skyworks FEM. Designed for maximum range and sensitivity, it delivers up to +31dBm output power and outstanding -124dBm receiver sensitivity at 1.2kbps. Supporting ISM bands (868MHz, 915MHz), it is the wireless solution for applications requiring kilometer-scale connectivity in smart metering, industrial automation, agricultural sensors, and long-range IoT networks.
Key Features
Exceptional Range & Sensitivity: Achieves >12 km line-of-sight range (at 1.2 kbps) with +31dBm transmit power and -124dBm receive sensitivity.
Frequency Support: Hardware optimized for ISM bands: 868MHz (EU), and 915MHz (USA).
Narrowband FSK Operation: Provides robust, interference-resistant communication in licensed-exempt bands, ideal for low-data-rate telemetry.
Complete & Compact Design: All RF circuitry, including the CC1120, FEM, and matching network, is integrated onto a single PCB. Requires minimal external components.
Standard SPI Interface: Controlled via a simple Serial Peripheral Interface (SPI), enabling easy integration with any host microcontroller.
Industrial Robustness: Operates reliably across an -30°C to +75°C temperature range, suitable for harsh environments.
