Microchip MRF24WB0MA Wi－Fi无线连接解决方案

1、microchip mrf24wb0ma wifi无线连接解决方案公司的mrf24wb0ma和mrf24wb0mb是低功耗2.4 ghz, ieee std. 802.11兼容的表面安装的rf模块,包括了全部的rf元件:晶振,旁路和偏压无源元件以及mac,基带,rf和功率,内置的硬件支持 aes和tkip (wep, wpa, wpa2 平安),数据速率为1和2 mbps,通信范围达400米,主要用于,消费类,工业控制和遥控设备.本文介绍了mrf24wb0ma/b主要特性,方框图,应用以及wi-fi演示板主要特性,图和主要元件布局图.the mrf24wb0ma and mrf24wb0mb

2、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 mod

3、ule 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 meander antenna.the mrf24wb0mb comes with an ultra miniature coaxial connector (u.fl) and is ap

4、proved for use with a list of pre-certified antennas.the mrf24wb0ma/mrf24wb0mb modules are designed to be used with microchips tcp/ip software stack. the software stack has an integrated driver that implements the api that is used in the modules for command and control, and for management and data p

5、acket traffic.the combination of the module and a running the tcp/ip stack results in support for ieee standard 802.11 and ip services. this allows, the immediate implementation of a wireless web server.the mrf24wb0ma/mrf24wb0mb modules have received regulatory approvals for modular devices in the u

6、nited states (fcc), canada (ic), and europe (etsi). the modular approval removes the need for expensive rf and antenna design, and allows the end user to place the modules inside a finished product and not require regulatory testing for an intentional radiator (rf transmitter).mrf24wb0ma/b主要特性:ieee
