RFM98The transceiver hasLoRa ™Remote modems that provide ultra-long distance spread spectrum communications and high immunity to interference while minimizing current consumption.

useLoRa ™Patented modulation technology,RFM98You can use low-cost crystal and material list to achieve more than-148dBmThe sensitivity. High sensitivity and integration+20 dBmThe combination of power amplifiers produces industry-leading link budgets that make it ideal for any application in the required range or robustness.

Compared with conventional modulation technology,LoRa ™In the blocking and selectivity also has a significant advantage to solve the traditional design in the range, anti-jamming capability and energy consumption between the compromise.

These devices also support inclusionWMBus,IEEE802.15.4gThe high performance of the systemG)FSKmode.RFM98Provides superior phase noise, selectivity, receiver linearity andIIP3, Significantly lower current consumption compared to competing devices.
