Qhov tseem ceeb ntawm RF lim

Vim li cas RF cov ntxaij lim dej tau dhau los ua qhov tseem ceeb dua?

Kev loj hlob sai ntawm cov ntaub ntawv xov tooj ntawm tes wireless thiab 4G LTE tes hauj lwm tau ua rau muaj kev xav tau ntau ntxiv rau cov bands tshiab thiab rau cov neeg nqa khoom sib sau ua ke los ua ke cov bands kom haum rau cov tsheb khiav wireless.Lub 3G network siv tsuas yog tsib pawg, thiab LTE tes hauj lwm tam sim no siv ntau dua 40 bands, thiab nrog rau qhov tshwm sim ntawm 5G, tus naj npawb ntawm bands yuav nce ntxiv.

Cov khoom siv sib txuas xa cov teeb liab hla ntau pawg: cellular, Wi-Fi, Bluetooth, thiab GPS, thaum zam kev cuam tshuam.Tej zaum peb yuav xav tam sim ntawd ntawm cov xov tooj smartphones, shark fins mounted rau saum lub tsheb, cellular base stations, radar thiab kev sib txuas lus systems, thiab industrial, scientific, los yog kev kho mob daim ntawv thov txuas nrog rau Internet ntawm yam (IoT).Lub sijhawm no, lub lim yuav tsum tau tawm los.

Lub smartphone tsis muaj lim yog cib

Zoo li cov kav hlau txais xov, cov ntxaij lim dej tau dhau los ua ib feem tseem ceeb ntawm kev sib txuas sib txuas.Cov cuab yeej tau txais ntau qhov ntau zaus, thiab lub lim tso cai rau qhov xav tau ntau zaus dhau los thaum ua kom tsis txhob muaj qhov tsis xav tau.Hauv lwm lo lus, cov lim dej zoo li Gandalf hauv John Ronald Ryall Tolkien's "Tus Tswv ntawm Rings": "Koj yuav tsis dhau!""Hnub no cov khoom siv feem ntau yog nruab nrog 30 mus rau 40 cov ntxaij lim dej kom tsis txhob cuam tshuam. Qhov xwm txheej no yuav nyuaj dua vim cov tiam tom ntej ntawm high-end smartphones yuav tsum tau lim ntau dua.

Lim tsim kev sib tw

Cov lim dej yog cov cuab yeej tseem ceeb rau RF tsim engineers, tab sis lawv kuj ntsib ntau yam teeb meem.Rau kev pib, kev ua haujlwm ntawm lub lim nws txawv nrog qhov kub thiab txias.Cov lim dej hauv ntau yam khoom siv niaj hnub no tuaj yeem tiv taus qhov kub nruab nrab ntawm 60 degrees Celsius (140 degrees Fahrenheit) lossis siab dua, thaum cov ntxaij lim dej sab hauv tuaj yeem tiv taus qhov nruab nrab ntawm 25 degrees Celsius (77 degrees Fahrenheit) thiab txawm tias kub dua rau shark fins lossis lim embedded hauv lub ru tsev.Qhov siab dua qhov ntsuas kub ntawm lub lim, qhov nyuaj yog lim tawm ib qho zaus, thiab qhov ntau dua yog tias lub teeb liab yuav "drift" mus rau cov kab uas nyob ib sab.

Kev tswj qhov kub thiab txias yog qhov tseem ceeb tshwj xeeb vim tias ntau qhov kev faib tawm tshiab tau nyob ze rau cov kab uas twb muaj lawm.Nyob rau tib lub sijhawm, kev sib sau ua ke ntawm cov neeg nqa khoom (CA) tau loj hlob sai, nrog rau cov chaw muab kev pabcuam ntawm tes sib txuas txog tsib tus neeg nqa khoom los ua pov thawj kev ua haujlwm hauv network, qhov kev lim dej meej yog qhov yuav tsum tau ua ua ntej.

Txhawm rau hais txog qhov kub thiab txias, kev lag luam RF tab tom tsim cov tshuab lim dej uas tsis muaj drift thiab drift-free filter technologies.Surface Sonic (SAW) thiab Lub Cev Suab Wave (BAW) cov ntxaij lim dej ua kom muaj kev ruaj ntseg siab thaum hloov pauv kub, ua tau raws li qhov xav tau ntawm kev ua haujlwm ntawm cov khoom siv tshiab.

Raws li tau hais los saum no, tiam tom ntej ntawm high-end smartphones kuj yuav tsum tau nruab nrog ntau cov ntxaij lim dej.Zoo li tag nrho lwm cov khoom ntawm rf, muaj chav me me rau cov ntxaij lim dej.Cov kws ua haujlwm yuav tsum muaj peev xwm sib xyaw ntau cov lim dej rau hauv qhov chaw me me kom ua tau zoo dua.

Duplexers, triplexers, cuadruplexers thiab hexaplexers tau sau ua ke hu ua multiplexers.Multiplexers sib xyaw ua ke ntau cov ntxaij lim dej rau hauv ib lub cuab yeej los pab cov neeg tsim qauv txuag chaw, ua kom yooj yim tsim, ua tau raws li qhov yuav tsum tau ua, thiab tsis txhob cuam tshuam.

 

Nyob rau hauv niaj hnub mobile ib puag ncig, tus naj npawb ntawm bands yuav tsum tau rau ib tug ntaus ntawv yog staggering, thiab nrog rau lub advent ntawm lub 5G era, qhov no qauv tsuas yog mus zuj zus.Thaum txhawb nqa tag nrho cov bands tuaj yeem ua rau muaj teeb meem cuam tshuam, qhov teeb meem tuaj yeem daws tau nrog lub lim.Yog tsis muaj cov ntxaij lim dej, lub network tsuas yog tsis ua haujlwm.
