RFM98

RFM95/96/97/98（W） RFM95/96/97/98(W) - Low Power Long Range Transceiver Module GENERAL DESCRIPTION The RFM95/96/97/98(W) transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using Hope RF‟s patented LoRaTM modulation technique RFM95/96/97/98(W) 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. LoRaTM 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 RFM95/96/97/98(W) deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
