HopeRF LoRa rf module

General Description

The RFM96W transceivers are equipped with the LoRa™ long-range modem, providing ultra-long range spread spectrum communication with high interference immunity while minimizing current consumption. These transceivers utilize Hope RF’s patented LoRa™ modulation technique, achieving a remarkable sensitivity of over -148dBm using cost-effective components. The combination of high sensitivity and an integrated +20 dBm power amplifier results in an industry-leading link budget, making the RFM96W ideal for applications that demand significant range and robustness. LoRa™ also offers considerable improvements in blocking and selectivity compared to conventional modulation techniques, effectively addressing the traditional trade-offs between range, interference immunity, and energy efficiency.

Additionally, the RFM96W supports high-performance (G)FSK modes suitable for systems including WMBus and IEEE802.15.4g. These devices stand out with exceptional phase noise, selectivity, receiver linearity, and IIP3, all while consuming significantly less current than competing devices.
