general description
the rfm92 transceivers feature the loratm long range modem thatprovides ultra-long range spread spectrum communication and highinterference immunity whilst minimising current consumption.
using hope rf’s patented loratm modulation technique rfm92 canachieve a sensitivity of over -137.5 dbm using a low cost crystaland bill of materials. the high sensitivity combined with theintegrated +20 dbm power amplifier  yields  industry leading  link  budget  making  it optimalfor any application requiring range or robustness. loratm alsoprovides significant advantages in both blocking and selectivityover conventional modulation techniques, solving the traditionaldesign compromise between range, interference immunity and energyconsumption.
these devices also support high performance (g)fsk modes forsystems including wmbus, ieee802.15.4g. the rfm92 deliverexceptional phase noise, selectivity, receiver linearity  and iip3  for  significantly lower  currentconsumption than competing devices.
