【無(wú)線射頻芯片】-Skyworks和Ember ZigBee前端模塊參考設(shè)計(jì)

1/1Skyworks和EmberZigBee前端模塊參考設(shè)計(jì)Ember公司的EM250是單片ZigBee解決方案,集成了2.4GHz,IEEE802.15.4兼容的收發(fā)器以及16位XAP2b微處理器,128KB閃存和5KBSRAM存儲(chǔ)器與基于ZigBee應(yīng)用的外設(shè).收發(fā)器允許和IEEE802.11g與藍(lán)牙共存,接收靈敏度為-99dBm,輸出功率為+3dBm,主要用于建筑物自動(dòng)化和掌握,家庭自動(dòng)化掌握,家庭消遣掌握以及財(cái)產(chǎn)跟蹤等.本文介紹了EM250的主要特性,方框圖和應(yīng)用電路圖與所用材料清單.此外還介紹了采納EM250和Skyworks公司的SKY65335和SKY65337的ZigBee前端模塊參考設(shè)計(jì)的電路圖和材料清單(BOM).TwoSerialControllerswithDMA
