RFM95W-915S2

The RFM95W-915S2 from Hoperf is a Lora™ RFM95W transceiver module at 915MHz band in SMD package. It feature LoRa™ long range modem that provides ultra long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using patented LoRa™ modulation technique RFM95W can achieve a sensitivity of over -148dBm. The high sensitivity combined with the integrated +20dBm 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. Device also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The RFM95W deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
