CMM-9209-V4.0
Long Range 2.4GHz Transceiver Module
C-MAX
This module is limited to OEM installation ONLY
Description
The CMM-9209 module is a miniaturised long range 2.4GHz transceiver module based on EM Microelectronic’s RF transceiver EM9209. The module is highly optimized for long-range wireless application
requiring ultra low power consumption and short time-to-market. It offers a plug and play solution for
any EM9209 application without any additional hardware nor RF layout. Built in with a PCB strip
antenna, this small sized, low cost module provides an ideal solution to wireless 2.4GHz license-free
application worldwide.
The EM9209 is a low-voltage 2.4GHz transceiver IC with built-in link-layer logic permitting proprietary
wireless links in the license-free 2.400 … 2.4835 GHz ISM band. This solution is ideal for battery
operated wireless applications such as wireless sensors and control, toys, human interface devices,
security and metering networks.
