RFM218BW

RFM218BW (G)FSK Receiver Module

Description

The RFM218BW is an ultra-low power, high performance receiver module which suitable for ISM band

wireless applications (G) FSK RF receiver. The module is highly integrated, which simplifies the peripheral

materials needed in the system design. It supports the direct mode which means input antenna then

output data. It also supports Duty-Cycle operation mode, channel interception, high-precision RSSI,

power-on reset, noise output and other functions, which makes the application design more flexible and

achieves product differentiation design.
