Uruhare rwa RF front-end muri sisitemu y'itumanaho

Mu buryo bugezweho bw'itumanaho, Radio Frequency (RF) front-end igira uruhare runini mu gutuma itumanaho rikoresha insinga rikora neza. Ishyizwe hagati ya antene na digital baseband, RF front-end ifite inshingano zo gutunganya ibimenyetso byinjira n'ibisohoka, bigatuma iba ingenzi mu bikoresho bitandukanye kuva kuri telefoni zigendanwa kugeza kuri satelite.

RF Front-End ni iki?
Igice cy’imbere cya RF kigizwe n’ibice bitandukanye bikora ku kwakira no kohereza ibimenyetso. Ibintu by’ingenzi birimo amplifiers z’amashanyarazi (PA), amplifiers z’urusaku ruke (LNA), filters, na switches. Ibi bice bikorana kugira ngo ibimenyetso byohererezwe mu buryo bufatika kandi busobanutse neza, mu gihe bigabanya urusaku n’ihungabana ry’itumanaho.

Ubusanzwe, ibice byose biri hagati ya antene na transceiver ya RF byitwa RF front-end, bigatuma habaho kohereza neza amajwi adafite umugozi.

2) Gushyira mu byiciro n'imikorere ya RF Front-End
Igice cya RF gishobora gushyirwa mu byiciro bibiri by'ingenzi hashingiwe ku miterere yacyo: ibice bitandukanye na module za RF. Ibice bitandukanye bishyirwa mu byiciro hashingiwe ku mikorere yabyo, mu gihe module za RF zigabanijwemo urwego rwo hasi, ruri hagati, n'ururerure rwo kwihuza. Byongeye kandi, bitewe n'inzira yo kohereza ibimenyetso, igice cya RF kirimo inzira zo kohereza no kwakira.

Kuva mu gice cy’imikorere cy’ibikoresho bitandukanye, ibice by’ingenzi bya RF imbere-nyuma birimo amplifier y’amashanyarazi (PA), duplexer (Duplexer na Diplexer), switch ya radiyo (Switch), filter (Filter) na amplifier y’urusaku ruke (LNA), nibindi. Ibi bice, hamwe na chip ya baseband, bigize sisitemu yuzuye ya RF.

Amplifaya z'amashanyarazi (PA): Kongera imbaraga z'ikimenyetso kiri koherezwa.
Duplexers: Gutandukanya ibimenyetso byo kohereza no kwakira, bigatuma ibikoresho bisangiza antene imwe neza.
Guhindura umurongo wa radiyo (Guhindura): Koresha uburyo bwo guhinduranya hagati yo kohereza no kwakira cyangwa hagati y'imirongo itandukanye y'umurongo wa radiyo.
Akayunguruzo: Gushungura imirongo idakenewe no kugumana ikimenyetso wifuza.
Amplifaya zikoresha urusaku ruto (LNA): Yongera ibimenyetso bidakomeye mu nzira yo kwakira.
Moduli za RF, hashingiwe ku rwego rwazo rwo guhuza, zihera kuri modules zoroshye (nka ASM, FEM) kugeza kuri modules zoroshye (nka Div FEM, FEMID, PAiD), na modules zoroshye (nka PAMiD, LNA Div FEM). Buri bwoko bwa module bwagenewe guhaza ibyifuzo bitandukanye bya porogaramu.

Akamaro mu buryo bw'itumanaho
RF front-end ni ingenzi mu gutuma itumanaho rikoresha insinga rikora neza. Igena imikorere rusange ya sisitemu mu bijyanye n'imbaraga z'amajwi, ubwiza, na bandwidth. Urugero, mu miyoboro ya telefoni, RF front-end igenzura itumanaho risobanutse hagati y'igikoresho n'aho giherereye, bigira ingaruka ku buryo butaziguye ku bwiza bw'itumanaho, umuvuduko w'amakuru, n'urugero rw'aho amakuru aturuka.

Ibisubizo bya RF byabugenewe imbere
Apex yihariye mu gushushanya ibice bya RF byihariye, itanga ibisubizo byabugenewe kugira ngo bihuze n'ibisabwa byihariye bya sisitemu zitandukanye z'itumanaho. Urutonde rwacu rw'ibicuruzwa bya RF by'imbere rutuma habaho imikorere myiza mu itumanaho, mu kirere, mu by'umutekano, n'ibindi.

Umwanzuro
Uburyo bwa RF bukoreshwa mu gutumanaho ni ingenzi cyane, butuma habaho kohereza no kwakira neza ibimenyetso, ariko bugagabanya uburyo bwo kubibangamira. Bitewe n’iterambere mu ikoranabuhanga no kwiyongera kw’ibikenewe kugira ngo imikorere irusheho kuba myiza, akamaro k’uburyo bwiza bwo gukoresha RF bukoreshwa mu gutumanaho gakomeje kwiyongera, bigatuma biba ingenzi mu miyoboro igezweho ya interineti idafite insinga.
