Transformers za RF zo guhuza Antena no guhuza imbere

A Transformer ya Rf Guhuza antene akenshi bitoranywa mu gihe cy'umushinga, ariko bishobora gufata icyemezo niba radiyo, module y'itumanaho cyangwa ikibaho cyo gupimira bishobora guhindurwa hatabayeho kongera guhindurwa. Mu miyoboro ya antene, guhuza imbere n'ibikoresho bya RF bito, iki gice si ikintu kiri mu murongo 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 rufite akamaro rugomba gufasha injeniyeri kugereranya imikorere y'amashanyarazi ishoboka, 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 ya RF bishobora gukoreshwa mu gushyigikira guhindura impedance cyangwa guhuza aho imyitwarire ya antene ihinduka bitewe n'aho ifungiye, insinga n'imiterere yo kuyishyiraho. Iyo nshingano igomba kuba isobanutse neza mbere yuko ikiganiro ku nimero y'igice 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, umurongo w'ingufu, igihombo cyo kwinjira, parasites zo mu ipaki no gutunganya antene ya nyuma. 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.

Mu gikoresho gito gikoresha insinga, antene ishobora kuba iri hafi ya bateri, pulasitiki, uduce tw'icyuma cyangwa amaboko y'umukoresha. Guhitamo transformateur bigomba gusiga umwanya wo gukosora bwa nyuma aho gukoresha umuti muto. 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 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 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 TCD-9-1W+, TC1-1-13M+ na DBTC-12-4-75+ 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 by’ikoranabuhanga, abashushanya module za RF n’amatsinda ashinzwe kugura ashyigikira ibikoresho bidafite insinga, 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, umurongo w’imikorere, umupaka w’ipaki, intego yo gutakaza, ibisabwa ku giciro, ikiguzi cyo kugaruka kw’igihombo 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 ugutekereza ko antene ihuye nayo yakozwe mbere yuko ibicuruzwa n'inzira y'insinga birangizwa. Niyo mpamvu urupapuro rudakwiye kurenza urugero. Ibice bya RF bidakora n'ibya 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 jwi ni nziza ku bahanga kuruta ibivugwa muri rusange ku bijyanye no guhuza ibintu byose.

Icyiza Transformer ya Rf Urupapuro rwo guhuza antene 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 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.
