Guhitamo paki ya RF Transformer yo guteranya SMT

SMD Transformer ya Rf Guhitamo paki akenshi bitoranywa nyuma y’umushinga, ariko bishobora gufata icyemezo niba radiyo, module y’itumanaho cyangwa ikibaho cyo gupimira bishobora guhindurwa hatabayeho guhindurwa bundi bushya. Muri module za RF zifite ubucucike bwinshi n’ibibaho bya SMT, iki gice si ikintu kiri mu murongo w’ibikoresho gusa. Ni igice cy’inzira y’ibimenyetso, igice cya gahunda ya impedance kandi, mu bicuruzwa byinshi, ni kimwe mu bituma ikibaho kimwe kitwara neza kurusha ikindi mu gihe cyo kwemeza. Kubwibyo, urupapuro rw’ibicuruzwa rufite akamaro rugomba gufasha abahanga mu by’ikoranabuhanga kugereranya imikorere y’amashanyarazi ishoboka, atari amazina y’ibirango gusa cyangwa ibirego by’abatanga serivisi bagutse.

Ingingo ya mbere yo guhitamo ni imikorere y'igice. Bitewe n'igishushanyo mbonera, ibice bya transformer bya SMD RF bishobora gukoreshwa mu guhuza imikorere ya RF n'imiterere ya pad ikorwa, kwihanganira gushyirwaho no kugenzura umusaruro. Iyo nshingano igomba kuba isobanutse neza mbere yuko ikiganiro ku mibare y'ibice gitangira. Transformer ya RF ya 1:1, 1:4 Transformateur y'ingufu, transformateur ya RF ya 50 ohm na transformateur ya RF balun yagutse byose bishobora kugaragara mu bicuruzwa bisa bya RF, ariko bikemura ibibazo bitandukanye. Iyo inshingano igenwe, akayunguruzo gakurikiraho ni idirishya ry'amashanyarazi: ipaki, aho umuntu anyura, uburebure, imiterere ya pad, igihombo cyo kwinjira n'igihombo cyo kugarura ibicuruzwa. Izi ndangagaciro zibwira injeniyeri niba umukandida ari ku rutonde rwa mbere rw'abagomba gutorwa cyangwa ko agomba gukurwaho mbere yuko ingero zisabwa.

Imbonerahamwe y'ibicuruzwa bya EASTEVER igomba koroshya ibyo byemezo ikerekana Zo(ohm), impedance ratio, Package, Min(MHz), Max(MHz), IL, Phase, Amp na Input RL. Zo(ohm) na impedance ratio bisobanura ibidukikije by'imikorere n'intego yo guhindura. Min(MHz) na Max(MHz) bigaragaza niba igice gikubiyemo umurongo nyawo w'imikorere aho kuba ahantu ho hagati horoshye. IL, cyangwa igihombo cyo gushyiramo, kirinda ingengo y'imari y'ikimenyetso. Phase na Amp ingana ni ingenzi igihe cyose circuit ikoresha ports za RF ziringaniye, receivers differential cyangwa balun conversion. Input RL ifasha injeniyeri gusuzuma reflection ku ruhande rw'isoko, ibyo bikaba ari ingenzi cyane hafi y'aho connectors, filters, RF switches na ports za IC.

Igice gikora neza mu gikoresho cya laboratwari gishobora kugorana mu bunini niba igishushanyo cya pad cyoroshye cyangwa ibice bigikikije bigatuma igenzura rikomera. Mu bikoresho nyabyo, uruziga rukikije akenshi ruhindura umusaruro kurusha uko byari byitezwe. Transformateur cyangwa igice cya rukuruzi kibona ubushobozi bwa pad, kugaruka k'ubutaka, imiterere ya solder, ingabo ziri hafi, kontaro zitangira ndetse rimwe na rimwe n'aho ibicuruzwa bifungirwa. Kubera iyo mpamvu, agaciro ka kataloge kagomba gufatwa nk'aho ari ho hatangirwa isuzuma ry'ubuhanga. Icyemezo cya nyuma kigomba gushingira ku bipimo biri mu kibaho cy'ingenzi, hamwe n'imiterere imwe ya kontaro, kontaro, insinga na antene nk'uko ibicuruzwa bizakoresha mu gukora.

Uburyo bwo gusesengura nka TC1-1-13M+, TCD-10-4-75+ na TCM2-63WX+ ni ingirakamaro mu itumanaho hagati y’ubuhanga n’amasoko kuko busobanura ubwoko bw’imikorere buzwi. Bushobora kandi gufasha umuguzi gusobanura impamvu umushinga ukeneye gupakira hejuru y’ubutaka. Transformer ya Rf, 50 ohm Transformer ya Rf, transformer ya interineti cyangwa balun ifite umurongo wihariye w’impinduka. Ariko, icyitegererezo cy’icyitegererezo ntikigomba gutangwa nk’igisimbura cyikora. Ni byiza gusobanura ibice bya EASTEVER nk’uburyo bwo gusesengura. Igereranya rigomba kuba rikubiyemo umurongo wihariye w’impinduka, igipimo cya impedance, igihombo cyo kwinjira, uburinganire bw’ibyiciro n’ubwinshi bw’amajwi, igihombo cyo kugaruka, paki, uburebure bw’aho ibintu biherereye n’uko biboneka.

Imiterere ya IC nayo ifasha mu gutuma guhitamo birushaho kuba byiza. Utubati dukoresha AD9361, ADRV9002 na ADF4351 akenshi tuba dufite ibyo twiteze ku bijyanye na impedance, imiterere y’aho dukoresha cyangwa ingero z’utubati tw’isuzuma, ariko igice cy’isuzuma kigomba kuba gihuye n’ibicuruzwa nyabyo. Igishushanyo mbonera cy’isuzuma gishobora gukoresha balun, choke cyangwa transformer runaka kuko akabati k’isuzuma kari gafite umugozi, connector na layer stack. Iyo IC imwe yimuriwe muri radiyo ikoreshwa mu ntoki, akabati k’itumanaho gakoresha charger, ikarita yo kubona amakuru cyangwa gateway nto idafite insinga, guhitamo kwa passive bishobora gukenera guhinduka.

Ku bahanga mu by’inganda, abashushanya RF n’amatsinda ashinzwe amasoko bahuza imikorere n’umusaruro w’iteraniro, agaciro k’urupapuro rw’icyiciro rwanditse neza ni umuvuduko n’icyizere. Uru rupapuro rugomba gutuma umusomyi ahitamo neza mbere yo kohereza ikibazo. Rugomba kandi guha isoko ururimi ruhagije rwo kubaza ikibazo gikwiye: impedance ikenewe, umurongo w’imikorere, umupaka w’ipaki, intego yo gutakaza, ibisabwa ku giciro, icyitegererezo cy’igihombo cyo kugaruka ndetse niba igice kirimo gukoreshwa mu gishushanyo gishya cyangwa isuzuma ry’isoko ritandukanye. Ibi bigabanya amahirwe y’uko umuguzi asaba gusa nimero y’igice mu gihe injeniyeri agikeneye ko hagenzurwa ibiteganywa n’amashanyarazi.

Ikosa rikunze kugaragara mu guhitamo ni uguhitamo paki ntoya cyane hatabayeho kugenzura ko aho ishyirwa rihagaze, ubwiza bw'aho ihurira hamwe n'ubushobozi bwo gusubiramo RF. Niyo mpamvu urupapuro rudakwiye kurenza urugero. Ibice bya RF bidakora neza na rukuruzi bigira ingaruka zikomeye ku miterere n'imiterere ya sisitemu. Inyandiko yo guhitamo ikwiye ibwira umusomyi icyo igice gishobora gufasha gukemura, amakuru agomba kugereranywa n'impamvu ibizamini byo ku rwego rw'ikigo bigikenewe. Iyo mvugo ni nziza ku bahanga kuruta ibivugwa muri rusange ku bijyanye no guhuza ibintu byose.

SMD nziza Transformer ya Rf Urupapuro rwo guhitamo paki rugomba kuyobora umusomyi kuva ku byo porogaramu ikeneye kugeza ku kugereranya gupimika. Tangira n'imikorere, igabanyije na Zo (ohm) n'igipimo, emeza Min (MHz) na Max (MHz), gereranya IL, Phase, Amp na Input RL, hanyuma urebe niba paki n'imiterere bihuye. Nyuma y'ibyo, saba ingero hanyuma wemeze ku kibaho nyacyo. Iyi miterere ikorera injeniyeri za RF, injeniyeri z'ibikoresho, injeniyeri zo gutanga amasoko n'injeniyeri zindi kuko ihuza ububiko bw'ibicuruzwa n'ibyemezo bafata koko.
