The RFM95 transceivers feature the LoRa™ long-range modem that provides ultra-long-range spread spectrum communication and high interference immunity whilst minimizing current consumption. 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.
Highlighted Features
- RFM95 Transceiver offers the same solution as the RFM95W-868S2
- 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
- These devices also support high-performance (G)FSK modes for systems including WMBus, IEEE802.15.4g
- The RFM95 delivers exceptional phase noise, selectivity, receiver linearity, and IIP3 for significantly lower current consumption than competing devices
Applications
- Automated meter reading
