Module ya RF front-end: imbaraga nyamukuru y'igihe cya 5G

Module ya RF front-end (FEM) igira uruhare runini mu itumanaho rigezweho ridafite insinga, cyane cyane mu gihe cya 5G. Igizwe ahanini n'ibice by'ingenzi nka power amplifier (PA),akayunguruzo,icyuma gifata udupira dubini, switch ya RF naamplifier y'urusaku rwo hasi (LNA)kugira ngo habeho imbaraga, ituze n'ubwiza bw'ikimenyetso.

Akamashini gatanga ingufu gashinzwe kongera ikimenyetso cya RF, cyane cyane muri 5G, gasaba imikorere myiza cyane no kuba gafite umurongo ugororotse. Aka kamashini gahitamo ikimenyetso cyihariye cya frequency kugira ngo gasukure ibimenyetso bibangamira uburyo ibimenyetso bikoreshwa kugira ngo habeho ubuziranenge bw'uburyo ibimenyetso bitangwa. Mu gice cy'umuvuduko mwinshi, ibyuma bitanga umusatsi w'amajwi (SAW) n'ibyuma bitanga umusatsi w'amajwi (BAW) bifite ibyiza n'ibibi byabyo. Ibikoresho bitanga umusatsi w'amajwi (BAW) bikora neza mu gice cy'umuvuduko mwinshi, ariko igiciro ni kinini.

Itsindaicyuma gifata udupira dubiniIshyigikira sisitemu y'itumanaho ya FDD (FDD) kugira ngo ikore neza itumanaho ry'impande zombi, mu gihe switch ya RF ishinzwe guhindura inzira y'ibimenyetso, cyane cyane mu buryo bwa 5G bwinshi, busaba gutakaza cyane no guhindura vuba.amplifier y'urusaku rukeigenzura ko ikimenyetso gito cyakiriwe kidahungabanywa n'urusaku.

Bitewe n'iterambere ry'ikoranabuhanga rya 5G, module za RF front-end zirimo kwerekeza ku guhuza no gukora ibintu bike. Ikoranabuhanga rya SiP rihuza ibice byinshi bya RF hamwe, rinoza guhuza no kugabanya ikiguzi. Muri icyo gihe, ikoreshwa ry'ibikoresho bishya nka liquid crystal polymer (LCP) na modified polyimide (MPI) mu ishami rya antene rirushaho kunoza imikorere y'itumanaho ry'amajwi.

Udushya twa module za RF front-end twateje imbere iterambere ry'itumanaho rya 5G, kandi tuzakomeza kugira uruhare runini mu itumanaho rikoresha insinga mu gihe kizaza, bikazana amahirwe menshi yo guteza imbere ikoranabuhanga.
