Njira zoyankhulirana zopanda zingwe nthawi zambiri zimakhala ndi magawo anayi: mlongoti, kutsogolo-kumapeto kwa wailesi, moduli ya ma radio frequency transceiver, ndi purosesa ya sigino ya baseband.
Kubwera kwa nthawi ya 5G, kufunikira ndi mtengo wa tinyanga ndi mawayilesi akutsogolo akuchulukirachulukira. Kumapeto kwa mawayilesi akutsogolo ndi gawo lofunikira lomwe limasintha ma siginecha a digito kukhala ma siginecha opanda zingwe a wailesi komanso ndi gawo lofunikira panjira yolumikizirana opanda zingwe.
Malinga ndi ntchitoyo, ma radio frequency front-end amatha kugawidwa kukhala ma transmitting end Tx ndi Rx yolandila.
Malinga ndi zida zosiyanasiyana, RF kutsogolo-kumapeto akhoza kugawidwa mu mphamvu amplifiers (RF chizindikiro matalikidwe kumapeto transmitter),zosefera (kusefa kwa siginecha pama transmitter ndi wolandila kumapeto),amplifiers otsika phokoso (kukulitsa chizindikiro kumapeto kwa wolandila, kuchepetsa phokoso), masiwichi (kusintha pakati pa mayendedwe osiyanasiyana),Duplexer(kusankha kwa siginecha, kufananitsa zosefera), chochunira (kufananitsa kwa njira ya antenna), etc.
Sefa: ma frequency enieni a zipata ndi zizindikiro zosokoneza zosefera
The fyulutandiye chida chofunikira kwambiri cha discrete kumapeto kwa RF kutsogolo. Zimalola kuti zigawo zafupipafupi zomwe zili mu chizindikirocho zidutse ndikuchepetsa kwambiri zigawo zina zafupipafupi, potero kumapangitsa kuti chizindikirocho chikhale chotsutsana ndi kusokoneza ndi chiŵerengero cha signal-to-noise.
Diplexer/Multiplexer: Kudzipatula kwa ma siginecha/kulandira
The duplexer, yomwe imadziwikanso kuti mlongoti duplexer, imakhala ndi ma seti awiri a band-stop zosefera zokhala ndi ma frequency osiyanasiyana.
The duplexerimagwiritsa ntchito magawo afupipafupi a fyuluta yapamwamba, yotsika-pass kapena band-pass kuti ilole mlongoti womwewo kapena chingwe chotumizira kuti chigwiritse ntchito njira ziwiri zazizindikiro, motero zimathandiza kuti mlongoti womwewo ulandire ndi kutumiza zizindikiro za maulendo awiri osiyana.
Low phokoso amplifier(LNA): kumakulitsa chizindikiro cholandiridwa ndikuchepetsa kuyambitsa phokoso
The amplifier otsika phokosondi amplifier yokhala ndi chithunzi chaching'ono kwambiri. Ntchito yake ndikukulitsa chizindikiro chofooka cha wailesi chomwe chimalandiridwa ndi mlongoti ndikuchepetsa kuyambitsa phokoso. LNA imatha kupititsa patsogolo kukhudzika kwa wolandila, potero kukulitsa mtunda wotumizira wa transceiver.
Andi katswiri komanso wopanga zida za RF & Microwave, CMalingaliro a kampani Hengdu Jingxin Microwave Technology Co., Ltd imagwira ntchito popanga ndi kupanga zida zingapo zofananira komanso zopangidwa mwamakonda zomwe zimatsogola kuyambira pa DC mpaka 110GHz.
