Microchip公司的MRF24WB0MA和MRF24WB0MB是低功耗2.4 GHz, IEEE Std. 802.11兼容的表面安装的RF收发器模块,包括了所有的RF元件:晶振,旁路和偏压无源元件以及MAC,基带,RF和功率放大器,内置的硬件支持 AES和TKIP (WEP, WPA, WPA2 安全),数据速率为1和2 Mbps,通信范围达400米,主要用于智能电网,消费类电子,工业控制和遥控设备.本文介绍了MRF24WB0MA/B主要特性,方框图,应用电路图以及Wi-Fi演示板主要特性,电路图和主要元件布局图.

The MRF24WB0MA and MRF24WB0MB are low-power, 2.4 GHz, IEEE Std. 802.11-compliant, surface mount modules with all associated RF components – crystal oscillator, bypass and bias passives with integrated MAC, baseband, RF and power amplifier, and built-in hardware support for AES, and TKIP (WEP, WPA, WPA2 security).

The integrated module design frees the designer from RF and antenna design tasks and regulatory compliance testing, ultimately providing quicker time to market. The MRF24WB0MA module is approved for use with the integrated PCB meander antenna.

The MRF24WB0MB comes with an ultra miniature coaxial connector (U.FL) and is approved for use with a list of pre-certified antennas.

The MRF24WB0MA/MRF24WB0MB modules are designed to be used with Microchip’s TCP/IP software stack. The software stack has an integrated driver that implements the API that is used in the modules for command and c..
