style="text-indent:25px">FPGA的供電，為了充分實現(xiàn)5G的優(yōu)勢，設計人員需要使用更高頻率的無線電，通過整合更多集成型微波/毫米波收發(fā)器、現(xiàn)場可編程門陣列(FPGA)、更高速率的數(shù)據(jù)轉(zhuǎn)換器以及適合更小蜂窩的高功率低噪聲功率放大器(PA)，才能充分利用新頻譜，以滿足未來的數(shù)據(jù)容量需求。此外，這些5G蜂窩還將包含更多的集成天線，才能應用大規(guī)模多路輸入、多路輸出(MIMO)技術以實現(xiàn)可靠連接。因此，需要各種先進的電源為5G基站組件供電?，F(xiàn)代FPGA和處理器采用先進納米工藝制造，因為它們通常要在緊湊封裝內(nèi)的高電流條件下采用低電壓(<0.9V)執(zhí)行快速計算。此外，新一代FPGA需要更低的內(nèi)核電壓以大幅提高計算速度，同時又要求更高的I/O接口電壓，并且還需要額外的DDR存儲器供電軌。因此，單個FPGA實際上需要具有嚴緊容差的多個電壓和不同的額定電流，以實現(xiàn)操作。更重要的是，為了避免損壞，必須以正確的順序?qū)@些電壓軌的時序進行控制。5G未來已來，通信電源時至勢成。坪山區(qū)1kw

style="text-indent:25px">供電升壓化是指傳統(tǒng)的48V供電架構(gòu)在5G時代可用性下降，要求5G電源系統(tǒng)具備升壓供電的能力。由于5G主設備能耗相比2G/3G/4G有了大幅提升，且5G站點拉遠供電需求更多，如果繼續(xù)采用傳統(tǒng)的48V供電模式，線纜損耗和壓降增大，設備輸入端電壓很可能無法滿足正常的供電需求，供電升壓化逐漸成為5G電源的重要發(fā)展趨勢。配電精細化是指5G電源可實現(xiàn)精細化下電和配電，極大提升關鍵業(yè)務的可靠性和保障能力。5G業(yè)務相比2G/3G/4G業(yè)務更加多元化，不同的業(yè)務輕重緩急各不相同，不同業(yè)務的分層分級管理可以提升網(wǎng)絡的可靠性，并降低網(wǎng)絡運維OPEX。湖南正規(guī)通信電源</p></p><br
