RFM98W 433mhz Wireless Receiving Module
This RFM98W 433MHz Wireless Receiving Module exclusively operates at 433MHz frequency.
The RFM98W transceivers are equipped with the LoRaTM long-range modem, enabling ultra-long range spread spectrum communication with high interference immunity, all while minimizing current consumption.
By employing Hope RF’s patented LoRaTM modulation technique, the RFM98W achieves remarkable sensitivity exceeding -148dBm using cost-effective components such as a low-cost crystal and bill of materials. This exceptional sensitivity, combined with the integrated 20 dBm power amplifier, results in an industry-leading link budget, making the RFM98W ideal for applications requiring extensive range or robustness. Moreover, LoRaTM modulation offers significant advantages in both blocking and selectivity compared to conventional modulation techniques, effectively resolving the traditional design compromise between range, interference immunity, and energy consumption.
