RFM95W HopeRF LoRa transceiver RF module for IoT end sensor nodes

Product Introduction

The RFM95W transceivers are equipped with the LoRa™ long-range modem, renowned for its ultra-long range spread spectrum communication capabilities and exceptional interference immunity while minimizing power consumption. These transceivers leverage Hope RF's patented LoRa™ modulation technology, enabling a sensitivity of over -148dBm with an economical crystal and materials cost. Integrated with a +20 dBm power amplifier, the RFM95W offers a leading-edge link budget that is ideal for applications demanding extended range and robustness. LoRa™ excels in blocking and selectivity, offering substantial improvements over traditional modulation methods and striking a perfect balance between range, interference immunity, and energy efficiency.

Additionally, the RFM95W supports high-performance (G)FSK modes compatible with WMBus, IEEE802.15.4g standards, and more. It achieves exceptional phase noise, selectivity, receiver linearity, and IIP3, all with significantly reduced current consumption compared to other devices in the market.
