Igihombo cyo kugarura ibicuruzwa mu guhitamo transformer ya RF

A Transformer ya Rf Igihombo cyo kugarura ibicuruzwa gikunze gutorwa nyuma y’umushinga, ariko gishobora gufata icyemezo niba radiyo, module y’itumanaho cyangwa ikibaho cyo gupimira gishobora guhindurwa hatabayeho kongera guhindurwa. Mu mpinduka zo guhuza, aho gupima RF n’ibibaho bigenzurwa na impedance, 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 ipimwa, atari amazina y’ibirango gusa cyangwa ibirego by’abatanga ibicuruzwa benshi.

Ingingo ya mbere yo guhitamo ni imikorere y'igice. Bitewe n'igishushanyo mbonera, ibice bya transformer bya RF bishobora gukoreshwa mu kugabanya ingufu zigaragara aho transformer ihurira n'isoko, umuhuza cyangwa umuyoboro uhuza uturutse hejuru. Uwo murimo ugomba kuba usobanutse 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: RL yinjiye, Zo(ohm), gutangiza board, frequency range n'aho package ishyirwa. Izi ndangagaciro zibwira injeniyeri niba umukandida ari ku rutonde rwa mbere rw'abagomba gutorwa cyangwa niba 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.

Iyo transformer yicaye iruhande rw'umuhuza, igisubizo gipimwe ni uruvange rw'igice, pads, ground vias na launch geometry. RL yinjiye igomba kugenzurwa ku miterere yagenwe. Mu bikoresho nyabyo, circuit ikikije akenshi ihindura umusaruro kurusha uko byari byitezwe. Transformer cyangwa igice cya rukuruzi ibona ubushobozi bwa pad, kugaruka k'ubutaka, imiterere ya solder, ingabo zegereye, kontaro zo gutangiza connector 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 ya kontaro, kontaro, insinga na antene nk'uko ibicuruzwa bizakoresha mu gukora.

Uburyo bwo gusesengura nka TC1-1-13M+, TCD-13-4-75+ 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 imiyoboro ya ADF4351, AD9361 na RF detector akenshi tuba dufite ibyo twiteze ku bijyanye na impedance, imiterere y’aho dukorera 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 bya RF n'amatsinda y'ibizamini bagereranya ibice by'ibikoresho bigenzurwa, 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'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 ugufata igihombo cyo kugaruka nk'igitekerezo cya nyuma cya kataloge nubwo akenshi ari cyo gihitamo uburyo ikimenyetso gisa neza ku ntebe. Niyo mpamvu urupapuro rutagomba kurenza urugero. Ibice bya RF bidakora n'ibya magnetike 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 kuruta ibivugwa muri rusange ku bijyanye no guhuza ibintu byose.

Icyiza Transformer ya Rf Urupapuro rw'igihombo cyo kugarura amakuru rugomba kuyobora umusomyi kuva ku byo akenera mu ikoreshwa kugeza ku kugereranya gupimwa. Tangira n'imikorere, gabanya na Zo (ohm) n'igipimo, wemeze 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.
