LW313M
Mini 2.4GHz Transceiver Module
Introduction
The LW313-1/2M module is a miniaturised 2.4GHz transceiver module based on EM Microlectronic's low energy RF transceiver EM9201/02. The module is highly optimized for proprietary link application requiring ultra low power consumption and short time-to-market. It offers a plug and play solution for any EM9201 application without any additional hardware nor RF layout. Built in with an inverted-L PCB antenna, this small sized, low cost module provides an ideal solution to wireless 2.4GHz license-free applications worldwide. The EM9201/02 is a low-voltage 2.4GHz transceiver IC with built-in link-layer logic permitting proprietary wireless links in the 2.400 … 2.4835 GHz ISM band. It has a radio core with a low-IF architecture and GFSK modulation scheme being compliant with the emerging Bluetooth low energy technology standard.
