Detail

Parameters

N515AS CC1120 + PA/LNA High-Performance Narrowband RF Module

The N515AS is a high-performance narrowband RF transceiver module that integrates the TI CC1120 transceiver with an external Power Amplifier (PA) and Low-Noise Amplifier (LNA). Designed for demanding industrial applications, it operates in the 169, 433, 868, and 915 MHz ISM bands, delivering enhanced +25 dBm output power and -118 dBm receiver sensitivity. This combination provides robust, long-range communication for telemetry, SCADA, and other critical wireless systems where both range and link reliability are paramount.

Key Features

📡 Enhanced RF Performance: The integrated external PA and LNA significantly boost transmit power to +25 dBm and improve receiver sensitivity, creating a superior link budget for extended range and reliability in challenging environments.
🎯 Professional Narrowband Operation: Optimized for spectrally efficient communication with excellent selectivity and blocking performance, ideal for licensed-quality applications in the sub-1 GHz band.
🌍 Global Multi-Band Support: A single hardware platform supports major international frequency bands (169, 433, 868, and 915 MHz), enabling worldwide deployment.
🔋 Industrial-Grade Durability: Built to operate reliably in extended temperature ranges and harsh environmental conditions.
🛠️ Complete Developer Access: All control pins for the CC1120 and the external PA/LNA are accessible, offering full flexibility for custom system integration and firmware development via SPI.
