RFM95W-868S2

LoRa RFM95W-868S2 Low Power Long Range Transceiver Module 868MHz. 

The RFM69HCW is a transceiver module capable of operation over a wide frequency range, including the 315,433, 868 and 915MHz license-free ISM (Industry Scientific and Medical) frequency bands. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69CW offers the unique advantage of programmable narrow-band and wide- band communication modes The RFM69CW is optimized for low power consumption while offering high RF output power and channelized operation. Compliance ETSI and FCC regulations. In order to better use RFM69CW modules, this specification also involves a large number of the parameters and functions of its core chip RF69's,including those IC pins which are not leaded out. All of these can help customers gain a better understanding of the performance of RFM69CW modules, and enhance the application skills.

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.
