RF92/93
RF92/93 - 860 MHz to 1020 MHz Low Power Long Range Transceiver
LoRa
GENERAL DESCRIPTION
KEY PRODUCT FEATURES
The RF92/93 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 RFs patented LoRaTM modulation technique
RF92/93 can achieve a sensitivity of over -137.5 dBm 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
RF92/93 deliver exceptional phase noise, selectivity,
receiver linearity and IIP3 for significantly lower current
consumption than competing devices.
