The HopeRF RFM90W-433S2R is a professional-grade sub-GHz radio transceiver module built around the Semtech SX1276/78-compatible RFM90 IC. Engineered for long-range wireless sensor networks and LPWAN applications, it provides a complete RF solution in a compact 16x16mm form factor. The module’s architecture is optimized for extreme power efficiency, featuring highly configurable operating modes that allow developers to balance range, data rate, and battery life.
It delivers a maximum RF output power of +22dBm via its integrated power amplifier, coupled with a sensitivity of -148dBm for LoRa, enabling reliable links over several kilometers in clear conditions. The fully integrated frequency synthesizer offers precise control with a 0.95 Hz step, allowing fine-tuning for specific regional band plans. Its support for automatic Channel Activity Detection (CAD) and preamble detection simplifies the implementation of low-duty-cycle listening protocols, which is critical for battery-powered sensor nodes in IoT ecosystems.
