Product Description
The RFM95W transceivers use the LoRaTM long-range modem, which enables ultra-long range spread spectrum communication with high interference immunity and low current consumption. The LoRaTM modulation technique, patented by Hope RF, allows the RFM95W to achieve a sensitivity of over -148dBm with a low-cost crystal and a simple bill of materials.
The transceivers have an industry-leading link budget due to the high sensitivity and the integrated 20 dBm power amplifier, making them ideal for any application that requires range or robustness. LoRaTM also offers significant benefits in blocking and selectivity over conventional modulation techniques, addressing the common trade-off between range, interference immunity, and energy consumption.
