Transformers za RF zo gushyira hejuru ku marembo magufi adafite umugozi

Igikoresho cyo gushyira hejuru Transformer ya Rf Ku bijyanye n'irembo ridafite umugozi, akenshi ritoranywa nyuma y'umushinga, ariko rishobora gufata icyemezo niba radiyo, module y'itumanaho cyangwa ikibaho cyo gupimira bishobora guhindurwa hatabayeho guhindurwa bundi bushya. Mu marembo adafite umugozi, nodes za IoT na antene nto, iki gice si ikintu kiri mu gitabo cy'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 injeniyeri 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 ya RF bishobora gukoreshwa mu guhuza imikorere ya RF no guhuza imiterere y'ibice byinshi nta kibazo cyo guteranya cyangwa gutunganya. 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: ingano y'ipaki, intera y'ingufu, igihombo cyo gushyiramo, ubushobozi bwo gusoda n'imiterere ya antene iri hafi. Izi ndangagaciro zibwira injeniyeri niba umukandida ari ku rutonde rwa mbere rw'abagomba gusora cyangwa 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.

Urubaho rw'irembo rushobora guhuza RF, guhindura ingufu n'imiyoboro ya digitale mu gasanduku kamwe gato. Transformateur igomba gushyirwaho ubuhanga buhagije bwa RF kugira ngo hirindwe guhindura igishushanyo gito mu kazi katoroshye ko gutunganya. Mu bikoresho nyabyo, urusobe rw'amashanyarazi rukunze guhindura umusaruro kurusha uko byari byitezwe. Transformateur cyangwa igice cya rukuruzi kibona ubushobozi bwa pad, kugaruka k'ubutaka, imiterere ya solder, ingabo zegereye, kontaro zitangira gukururwa ndetse rimwe na rimwe n'agasanduku k'ibicuruzwa bya nyuma. Kubera iyo mpamvu, agaciro ka kataloge kagomba gufatwa nk'aho ari ho hatangirwa isuzuma ry'ubuhanga. Icyemezo cya nyuma kigomba gushingira ku gupima mu gasanduku kagenewe, hamwe n'imiterere imwe y'agasanduku, agasanduku, insinga na antene nk'uko ibicuruzwa bizakoresha mu gukora.

Uburyo bwo gusesengura nka TCM2-63WX+, TC1-1-13M+ na DBTC-10-13LX+ 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. Udupapuro dukoresha SX1262, CC1101 na ADF7021 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 byuma bya IoT n'amatsinda ashinzwe gushaka ibikoresho bubaka ibikoresho bito bidafite insinga, 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 umusomyi 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 paki igabanya umwanya ariko igatuma inzira ya RF iba nto cyane, ikaba ndende cyane cyangwa ikaba yakwangirika cyane ku kugaruka k'ubutaka. Niyo mpamvu urupapuro rudakwiye gusezeranya cyane. 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'inama bigikenewe. Iyo mvugo ni nziza ku bahanga kurusha uko bivugwa ku bijyanye no guhuza ibintu byose.

Igikoresho cyiza cyo gushyira ku buso Transformer ya Rf Ku rubuga rwa interineti rudafite umugozi, urupapuro rw’inzira rugomba kuyobora umusomyi kuva ku bikenewe kuri porogaramu kugeza ku kugereranya gupimwa. Tangira ku mikorere, gabanya 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.
