Transformers za RF Balun zo guhindura ibintu mu buryo buringaniye cyangwa butangana

Irimo kuringaniza kuva ku kutagira uburimbane Transformer ya Rf Balun Akenshi itoranywa nyuma y’umushinga, ariko ishobora gufata icyemezo niba radiyo, module y’itumanaho cyangwa ikibaho cyo gupimisha bishobora guhindurwa hatabayeho guhindurwa bundi bushya. Mu byambu bya IC, filters, antene n’inzira za coaxial, iki gice si ikintu cy’umurongo gusa mu gitabo cy’ibikoresho. 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 by’ingirakamaro rugomba gufasha injeniyeri kugereranya imikorere y’amashanyarazi ipimwa, atari amazina y’ibirango gusa cyangwa ibivugwa n’abatanga serivisi bagutse.

Ingingo ya mbere yo guhitamo ni imikorere y'igice. Bitewe n'igishushanyo mbonera, ibice bya transformer bya RF balun bishobora gukoreshwa mu guhindura hagati y'ibidukikije bya RF bitandukanye n'ibiri ku mpera imwe mu gihe bibungabunga impedance n'uburinganire. 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: igipimo, uburinganire bw'ibyiciro, uburinganire bw'amplitude, igihombo cyo kwinjira no guhuza inzira y'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.

Umuyoboro wa RF IC ugororotse akenshi ukenera guhinduka neza ukajya mu nzira imwe y’urufunguzo cyangwa antene. Iyo balun idatoranijwe hibandwa ku muyoboro wose, guhindura biba inzira yo kugerageza no gukora amakosa. Mu bikoresho nyabyo, uruziga rukikije akenshi ruhindura umusaruro kurusha uko byari byitezwe. Transformer cyangwa igice cya rukuruzi kibona ubushobozi bwa pad, kugaruka k’ubutaka, imiterere ya solder, ingabo zegereye, kontaro zitangira gukururwa 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 gupima mu kibaho cy’ingenzi, hamwe n’imiterere imwe y’aho ibicuruzwa bizakoresha mu gukora.

Ingero z'ifatizo nka TCM2-63WX+, TC1-1-13M+ na TCD-9-1W+ ni ingirakamaro mu itumanaho hagati y'ubuhanga n'amasoko kuko zisobanura ubwoko bw'imikorere buzwi. Zishobora 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. Udupapuro dukoresha AD9361, ADRV9002 na RDA1846S 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 ba RF n'amatsinda y'ibikoresho by'inyongera bakora ku mpera za transceiver, agaciro k'urupapuro rw'icyiciro rwanditse neza ni umuvuduko n'icyizere. Urupapuro rugomba gutuma umusomyi ahitamo neza mbere yo kohereza ikibazo. Rugomba kandi guha isoko ururimi ruhagije rwo kubaza ikibazo gikwiye: impedance ikenewe, umugozi wo gukora, umupaka w'ibicuruzwa, intego yo gutakaza, ibisabwa ku giciro, ikiguzi cyo kugaruka kw'ibicuruzwa 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 ugukoresha balun nk'adaptateri rusange utitaye ku niba umuyoboro wa IC, filter na antene byose byiteze ibidukikije bimwe bya impedance. Niyo mpamvu urupapuro rutagomba kurenza urugero. Ibice bya RF bidakora n'ibya rukuruzi bigira ingaruka zikomeye ku miterere n'imiterere ya sisitemu. Inyandiko yo guhitamo ireba umusomyi icyo igice gishobora gufasha gukemura, amakuru agomba kugereranywa n'impamvu ibizamini byo ku rwego rw'inama bigikenewe. Iyo jwi ni nziza ku bahanga kuruta ibivugwa muri rusange ku bijyanye no guhuza ibintu byose.

Uburyo bwiza bwo kuringaniza kuva ku kutaringaniza Rf Balun Urupapuro rwa transformer rugomba kuyobora umusomyi kuva ku byo akenera mu ikoreshwa kugeza ku kugereranya gupimwa. 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 package 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.
