RFM95/96/97/98

RFM95/96/97/98(W) - Low Power Long Range Transceiver Module
V1.0
GENERAL DESCRIPTION
The
RFM95/96/97/98(W) transceivers
feature
the
LoRaTMĀ Ā 
long range modem that provides ultra-long range
spread spectrum communication and high interference
immunity whilst minimising current consumption.
Using Hope RFā€™s patented LoRaTMĀ  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. LoRaTMĀ  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.
