915MHz LoRa/FSK Transceiver Module
General Description
RFM97CW Sub-GHz radio transceivers are
ideal for long range wireless applications. With
high integration, the RFM97CW simplifies the
peripheral materials needed in system design.
The sensitivity up to - 138dbm that optimizes
link performance for applications. In addition,
the RFM97CW also supports the function of
duty cycle operation mode, channel listening,
high-precision RSSI, power on reset, squelch
output, etc., which makes the application design
more flexible and realizes product differentiation
design. The working voltage of RFM97CW is
from 1.8V to 3.7V. When the sensitivity of -
138dbm is reached, only 9.9ma current is
consumed, and the ultra-low power
consumption receiving mode can further reduce
the receiving power consumption of the chip.
