 RFM92W 915Mhz 20dBm LoRa Transceiver

Description:
The RFM92W transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity—while minimizing current consumption. Using HopeRF's patented LoRaTM modulation technique, the RFM92W achieves a sensitivity of over -137.5 dBm using a low cost crystal and bill of materials. This high sensitivity combined with the integrated +20dBm power amplifier, yields an industry leading link budget—making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, thus 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 and IEEE802.15.4g. The RFM92W delivers exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
