Atenuator ni iki?

Attenuator nikintu cya elegitoronike gikoreshwa cyane mubikoresho bya elegitoroniki, kandi umurimo wacyo nyamukuru ni ugutanga attenuation. Nibintu bitwara ingufu, bihinduka ubushyuhe nyuma yo gukoresha ingufu. Intego zayo nyamukuru ni: (1) Guhindura ingano yikimenyetso mukuzunguruka; . . Noneho iyo ukoresheje attenuator, ni ibihe bibazo bikeneye kwitabwaho?

Reka tubitangire mu magambo arambuye hepfo:

1. Igisubizo cyinshyi: umurongo wumurongo, mubisanzwe bigaragarira muri megahertz (MHz) cyangwa gigahertz (GHz). Muri rusange intego-ya attenuator muri rusange ifite umurongo wa 5 GHz, hamwe nubunini ntarengwa bwa 50 GHz.

2. Urwego rwa Attenuation hamwe nimiterere:

Urwego rwa Attenuation rwerekana igipimo cya attenuation, muri rusange kuva kuri 3dB, 10dB, 14dB, 20dB, kugeza 110dB. Inzira ya attenuation ni: 10lg (iyinjiza / ibisohoka), kurugero: 10dB kuranga: ibyinjijwe: ibisohoka = attenuation inshuro nyinshi = 10. Imiterere igabanijwemo muburyo bubiri: igenamigambi rihamye hamwe nintambwe igereranya ihinduka. Umuyoboro uhamye bivuga attenuator ifite igipimo gihamye inshuro nyinshi murwego runaka. Intambwe yerekana ni attenuator ifite agaciro runaka gahamye hamwe nintera ingana ihinduka. Igabanijemo intoki intambwe yintambwe hamwe na programable intambwe ya attenuator.

3. Ifishi yumutwe uhuza nubunini bwihuza:

Ubwoko bwihuza bugabanijwe mubwoko bwa BNC, N ubwoko, ubwoko bwa TNC, ubwoko bwa SMA, ubwoko bwa SMC, nibindi. Mugihe kimwe, imiterere ihuza ifite ubwoko bubiri: umugabo numugore.

Ingano yo guhuza igabanijwemo sisitemu ya metero na imperuka, kandi ibyavuzwe haruguru bigenwa ukurikije ibisabwa byo gukoresha; niba ubwoko bwabahuza bugomba guhuzwa, adaptate ihuza ihuza irashobora kuba ifite ibikoresho, kurugero: BNC kugeza N-ihuza N, nibindi.

4. Icyerekezo cya Attenuation:

Ibipimo bya Attenuation bifite byinshi bisabwa, cyane cyane ibi bikurikira: kwizerwa kwukuri, kwihanganira imbaraga, inzitizi ziranga, kwizerwa, gusubiramo, nibindi.

Nkuwashushanyijeattenuator, Jingxin irashobora kugutera inkunga yubwoko butandukanye bwa attenuator ukurikije igisubizo cya RF.
