GENERAL DESCRIPTION

The ZM1278 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
Using ZK RF’s patented LoRaTM modulation technique ZM1278-TR can achieve a sensitivity of over -139 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 ZM1278-TR deliver exceptional phase noise, selectivity, receiver linearity  and  IIP3  for  significantly lower  current consumption than competing devices.
