Microchip MRF24WB0M 2.4GHz Wi-Fi收发方案

Microchip 公司的MRF24WB0MA和MRF24WB0MB是低功耗 2.4GHz IEEE Std. 802.11兼容的Wi-Fi收发模块，包括所有的RF元件如晶振，旁路和带MAC的偏压电路，基带，RF和功率放大器，内支硬件支持AES和TKIP (WEP, WPA, WPA2 安全加密).模块工作电压2.7V-3.6V，工作频率为ISM频段2.400-2.483.5 GHz，14路可选择，DSSS调制，数据速率1000kbps，1Mbps的灵敏度为-91dBm，典型输出功率为+10dBm，主要用在智能仪表，白色家电，消费类电子，工业控制，遥控设备管理，以及零售设备和医疗保健设备。本文介绍了MRF24WB0MA和MRF24WB0MB主要特性，方框图，和微控制器接口以及典型应用电路。

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 tasksand 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.
