Mu makina olumikizirana opanda zingwe, nthawi zambiri pamakhala zinthu zinayi: antenna, radio frequency (RF) front-end, RF transceiver, ndi baseband signal processor.
Pamene nthawi ya 5G yayamba, kufunika ndi phindu la ma antenna ndi ma RF front-ends kwakwera mofulumira. RF front-end ndiye chinthu chofunikira kwambiri chomwe chimasintha ma digital signals kukhala ma RF wireless signals, komanso ndi chinthu chachikulu cha machitidwe olumikizirana opanda zingwe.
Pantchito, mbali yakutsogolo ya RF ikhoza kugawidwa m'mbali yotumizira (Tx) ndi mbali yolandirira (Rx).
● Sefa: Imasankha ma frequency enaake ndikusefa zizindikiro zosokoneza
● Duplexer/Multiplexer: Imalekanitsa zizindikiro zotumizidwa/zolandiridwa
● Chokulitsa Mphamvu (PA): Chimakulitsa zizindikiro za RF kuti zigwiritsidwe ntchito potumiza
● Chokulitsa Phokoso Lochepa (LNA): Chimakulitsa zizindikiro zolandiridwa pamene chimachepetsa phokoso lomwe limayamba
● RF Switch: Imalamulira kuyatsa/kuzima kwa dera kuti ithandize kusintha kwa chizindikiro
● Chosinthira: Chofananitsa Impedance cha antenna
● Zigawo zina za RF kutsogolo
Chotsatirira ma envelopu (ET) chimagwiritsidwa ntchito kupititsa patsogolo mphamvu ya amplifier ya ma siginecha okhala ndi mphamvu zambiri zomwe zimafika pachimake mpaka pa avareji polola mphamvu yosinthika kutulutsidwa.
Poyerekeza ndi njira zotsatirira mphamvu zapakati, kutsatira ma envelopu kumalola magetsi a amplifier kutsatira ma envelopu a chizindikiro cholowera, zomwe zimapangitsa kuti mphamvu ya amplifier ya RF ikhale yogwira ntchito bwino.
Wolandira ma RF amalandira ma signal a RF kudzera mu antenna kudzera mu zigawo monga zosefera, ma LNA, ndi ma analog-to-digital converters (ADCs) kuti achepetse ndikuchepetsa ma signal, kenako nkupanga baseband signal ngati output.
Concept Microwave ndi kampani yopanga zinthu za 5G RF ku China, kuphatikizapo fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi directional coupler. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
