HOPERF Low Power High-performance LoRa Transceiver Module RFM91SC

Description:

The RFM91(SC) is an ultra-low power, high-performance LoRa transceiver module for a wide range of wireless applications from 410 MHz to 810 MHz.The RFM91(SC)'s high level of integration simplifies the peripheral materials required for system design, and its high sensitivity of up to -137 dBm optimizes the link performance of the application. In addition, the RFM91(SC) supports Duty-Cycle operation mode, channel listening, high-precision RSSI, power-on reset, squelch output, etc., which makes the application design more flexible and allows for product differentiation. The ultra-low-power receive mode further reduces the chip's receive power consumption.
