DL-RFM95 868/915Mhz Wireless FSK Transceiver Module
Brief Introduction
The 868/915Mhz RFM95 Wireless Transceiver Modules feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
Using LoRa modulation technique DL-RFM95 RF Transceiver Module can achieve a sensitivity of over -140dBm 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 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 DL-RFM95/96/98 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
