RFM95W-868S2 RFM95 LoRa Ultra-long Range Transceiver Module - GFSK GMSK LoRa OOK - 868MHz SPI - for IoT Automated Meter Reading (RFM95W) (RFM95W-868S2)

The RFM95W-868S2 transceivers features the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

Using the patented LoRa modulation technique RFM95 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness.

LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.

These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The RFM95 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
