Ngawaphi amacandelo afakwe kwi-RF front-end?

Iisistim zonxibelelwano olungenazingcingo zibandakanya ngokubanzi iinxalenye ezine: i-eriyali, isiphelo serediyo yerediyo, imodyuli yerediyo ye-transceiver, kunye neprosesa yesiginali ye-baseband.

Ngokufika kwexesha le-5G, imfuno kunye nexabiso lee-antenna kunye ne-radio frequency front-ends zikhula ngokukhawuleza.Isiphelo serediyo yerediyo licandelo elisisiseko eliguqula iisignali zedijithali zibe ziisignali zamaza erediyo ezingenazingcingo kwaye ikwalicandelo elingundoqo lenkqubo yonxibelelwano engenazingcingo.

Ngokomsebenzi, isiphelo serediyo yerediyo yangaphambili inokohlulwa ibe kwisiphelo sothumelo Tx kunye nesiphelo sokufumana i-Rx.

Ngokwezixhobo ezahlukeneyo, isiphelo sangaphambili se-RF sinokwahlulwa zibe ziamplifiers zamandla (ukukhulisa umqondiso weRF ekupheleni kokuhambisa),izihluzi (ukucoca umqondiso kwi-transmitter kunye nesiphelo somamkeli),iiamplifiers ezinengxolo ephantsi (ukukhulisa umqondiso ekupheleni kommkeli, ukunciphisa ingxolo), utshintsho (ukutshintsha phakathi kwamajelo ahlukeneyo),Duplexer(ukhetho lwesignali, ukuhambelana kokucoca), i-tuner (i-antenna signal channel impedance matching), njl.

Hluza: Isango elithile elijikelezayo kunye neempawu zokuphazamiseka kokucoca

I isihluzosesona sixhobo sibalulekileyo kwi-RF front-end.Ivumela amacandelo athile okwenziwa rhoqo kumqondiso ukuba adlule kwaye athomalalise kakhulu amanye amacandelo amaza, ngaloo ndlela iphucula i-anti-interference yesiginali kunye ne-signal-to-noise ratio.

Diplexer/Multiplexer: Ukwahlulwa kokuhambisa/ukufumana imiqondiso

I duplexer, ekwabizwa ngokuba yi-eriyali i-duplexer, iqulathe iiseti ezimbini ze band-stop izihluzi kunye frequencies ezahlukeneyo.

I duplexerisebenzisa umsebenzi wokwahlula rhoqo we-high-pass, i-low-pass okanye i-band-pass filter ukuze ivumele i-eriyali efanayo okanye umgca wothumelo ukuba usebenzise iindlela ezimbini zomqondiso, ngaloo ndlela ivumela i-eriyali efanayo ukufumana kunye nokuhambisa imiqondiso yeefrikhwensi ezimbini ezahlukeneyo.

Isandisi-lizwi esisezantsi(LNA): ikhulisa umqondiso ofunyenweyo kwaye inciphisa ukuqaliswa kwengxolo

I iamplifier yengxolo ephantsisisandisi-lizwi esinomzobo omncinci kakhulu wengxolo.Umsebenzi wayo kukwandisa isignali yefrikhwensi yerediyo ebuthathaka efunyenwe yi-eriyali kunye nokunciphisa ukwaziswa kwengxolo.I-LNA inokuphucula ngokufanelekileyo uvakalelo olufumanayo lomamkeli, ngaloo ndlela inyusa umgama wothumelo lwe-transceiver.

Akumvelisi ovunyiweyo kunye novelisa izinto ezintsha zeRF & Microwave, Chengdu Jingxin Microwave Technology Co., Ltd igxile ekuyileni nasekuveliseni uluhlu olubanzi lwamacandelo asemgangathweni kunye nesiko loyilo kunye nokusebenza okuphambili ukusuka kwi-DC ukuya kwi-110GHz. Ukuba unayo naziphi na iimfuno zevarious passive components, you are welcome to contact us @ sales@cdjx-mw.com
