HopeRF RFM69HW-868S2R Sub-1GHz RF Transceiver Module

Description

The HopeRF RFM69HW-868S2R is a versatile sub-1GHz ISM band RF transceiver module built around the RF69H core chip. It is engineered for reliable, long-range wireless communication in license-free 868MHz bands, offering developers full programmability over key RF parameters like data rate, output power, and modulation scheme. Its architecture is optimized for low current draw while delivering high RF output power, making it ideal for power-constrained remote sensing applications.

The module features a highly selective 16-tap FIR channel filter and robust front-end performance with an IIP3 of -18 dBm and 80 dB blocking immunity, ensuring stable operation even in the presence of strong interferers. Its integrated bit synchronizer handles clock recovery automatically, simplifying data packet processing. The constant RF performance across the operating voltage range and compliance with ETSI/FCC regulations provide a reliable foundation for commercial and industrial IoT deployments.
