在你的下一個(gè)無線系統(tǒng)設(shè)計(jì)中使用射頻板和EV套件評(píng)估芯片特性

　　隨著支持無線通信系統(tǒng)的芯片越來越復(fù)雜，開發(fā)板和評(píng)估模塊提供了一種快速檢查芯片性能和功能的方法。由于開發(fā)板或評(píng)估包已經(jīng)正確地連接了電源、接地、偏置和輸入和輸出信號(hào)傳輸，所以當(dāng)評(píng)估芯片時(shí)，電路板首次解決了許多挑戰(zhàn)。此外，電動(dòng)車板的物理設(shè)計(jì)也提供了屏蔽和接地平面布局的見解，以確保芯片提供最佳性能。這通?？梢栽谠u(píng)估階段節(jié)省多個(gè)天數(shù)，從而為設(shè)計(jì)者提供更多的測(cè)試時(shí)間。

　　這些委員會(huì)包括線路板面積，使設(shè)計(jì)人員能夠通過添加一個(gè)特殊的接口，傳感器定制板，或其他電路，使關(guān)鍵部分的系統(tǒng)能夠?qū)崿F(xiàn)并允許設(shè)計(jì)師證明了其設(shè)計(jì)的功能。在最終的系統(tǒng)設(shè)計(jì)階段，這將最大限度地減少潛在的再旋轉(zhuǎn)風(fēng)險(xiǎn)。

　　The wide variety of development/evaluation boards for single-chip wireless LAN transceivers， FSK/ASK ISM-band highly-integrated mixer-receivers， L-band tuner transceivers， downconversion mixers， and even specialty functions such as key fob transmitters， logarithmic amplifiers， and others， provides designers with tools that can shorten their development cycles. This article will take a look at several of the higher-end evaluation kits/development boards to examine the features offered and how designers can take advantage of these features.
