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

GENERAL DESCRIPTION

The

RFM95/96/97/98(W) transceivers

feature

the

LoRa^TMlong range modem that provides ultra-long range

spread spectrum communication and high interference

immunity whilst minimising current consumption.

Using Hope RF’s patented LoRa^TMmodulation 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. LoRa^TMalso provides significant advantages in

both blocking and selectivity over conventional modulation

techniques, solving the traditional design compromise

between range, interference immunity and energy

consumption.

RFM95/96/97/98(W)

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.
