style="text-indent:25px">正是由于巨大的市場空間以及對產(chǎn)業(yè)和技術(shù)的巨大推動力，5G吸引著世界各大國和主流運營商加入激烈的角逐當(dāng)中，因為盡早大規(guī)模商用5G網(wǎng)絡(luò)的國家，能夠大概率鞏固現(xiàn)有的產(chǎn)業(yè)優(yōu)勢，并進一步擴大全球影響力。目前來看，5G的一波市場主要聚焦在中國、美國、韓國、歐洲和中東等國家和區(qū)域，其中中國、美國和韓國為積極：中國三大運營商目前已完成5G頻譜分配，2019年預(yù)商用，2020年將全方面商用；美國運營商Verizon已于2018年下半年發(fā)布基于5G的FWA業(yè)務(wù)，2019年開始規(guī)模部署；韓國3家運營商LGU+、SKT、KT應(yīng)**要求于2018年年底發(fā)布商用5G，2019年開始大規(guī)模部署。歐洲、中東等國家運營商為了爭奪先機和話語權(quán)，也在加速5G的部署。羅湖區(qū)5G通信電源模塊天磁科技主要從事于充電模塊、大功率電源、雙向電源、儲能PCS以及儲能系統(tǒng)等。</p><div

style="text-indent:25px">一般來說，模塊在上板前都會進行功能測試，驗證模塊的電壓輸出是否正常。電源模塊輸出有電壓但電壓低于標(biāo)稱輸出值是測試過程中經(jīng)常遇到的問題，出現(xiàn)這種情況的原因無非有兩種，一是電源模塊為不良品或損壞，二是使用方法問題。下文天磁將重點討論使用方法導(dǎo)致的電源模塊輸出電壓低的情況。輸入電壓偏低是容易被忽略的情況，當(dāng)輸出有問題時我們應(yīng)該一時間檢查輸入是否正常。對于輸入為定壓或?qū)拤旱碾娫茨K，當(dāng)輸入值偏低時將導(dǎo)致輸出值也偏低。當(dāng)然，這種情況是有限度的，對于一個特定的模塊來說，當(dāng)輸入電壓過低時將導(dǎo)致其不能工作，無輸出電壓。輸出過載是指負載工作功率大于電源模塊的額定輸出功率，過載情況下電源模塊的輸出電壓明顯被拉低。以ZY0505FS-1W為例，當(dāng)負載電流增大到300mA時，輸出電壓只有4.5V。持續(xù)過載將影響到電源模塊的工作效率、穩(wěn)定性以及散熱情況，導(dǎo)致模塊使用壽命減少。若是過載導(dǎo)致的輸出電壓過低，則需要提升電源模塊的輸出功率，可以選擇2W或3W的模塊。</p><p

PA所需的效率(>90%)、功率密度、低噪聲性能和控制功能。在新一代(5G)產(chǎn)品性能必須超越上一代(4G)的巨大壓力下，幾乎沒有任何折衷的余地。5G產(chǎn)業(yè)報告之電源市場，歡迎咨詢天磁。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
