RFM95/96/97/98W
RFM95/96/97/98(W) - Low Power Long Range Transceiver Module V1.0
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.
