Ibipimo bya 75 ohms 75Ω Bihamye 75 ohms Bihamye
Attenuator ya 75 ohms ni ubwoko bwa attenuator bwitiriwe impedance yayo ya 75 ohms.
Ni igice kidakora gikoreshwa mu kugenzura imbaraga z'ikimenyetso cy'urukiramende, Attenuator ya 75Ω irinda kwiyongera cyane no guhindagurika kw'ikimenyetso, kandi ikarinda gutsindwa guterwa no kurenza urugero rw'ikimenyetso.
Ibiranga by'ingenzi bya 75Ω attenuators zihoraho birimo:
1. Guhuza Impedance: Impedance ya 75 Ohms idahinduka ihuye n'impedance iranga umurongo wo kohereza ibimenyetso by'ibikoresho bya videwo, televiziyo na televiziyo y'insinga, bityo bigabanye urumuri n'igihombo cy'ikimenyetso cyo kohereza.
2. Kugoreka guke: Attenuator ishobora kugabanya imbaraga z'ikimenyetso idashyizeho ubundi buryo bwo kugoreka cyangwa kubangamira ikimenyetso.
3. Kwizerwa cyane: Bitewe nuko ibikoresho bigabanya ubushyuhe ahanini ari ibice bidakora kandi bitagira ibice bigenda, birizewe cyane kandi ntibisaba kwitabwaho cyangwa gusimburwa.
Ibikoresho bigabanya ubushyuhe bya 75 ohms bikunze gukoreshwa muri ibi bikurikira:
1. Mu miyoboro ya televiziyo ya cable na televiziyo ya digitale, ikoreshwa mu kugenzura imbaraga z'amajwi no kugabanya ubwiza bw'amajwi n'igihombo.
2. Mu gihe cyo gukora no kohereza videwo zifite ubushobozi bwo hejuru n'ubuhanga bwo hejuru, genzura imbaraga z'ikimenyetso kandi ukomeze kugira ubuziranenge bwo guhindura.
3. Muri sisitemu zo kohereza amatangazo ya televiziyo na televiziyo, ibikoresho bihindura imbaraga z'amatangazo kugira ngo bihuze n'uburyo bwihariye bwo gutunganya amatangazo yakwirakwijwe kandi bikongera urwego rw'amatangazo.
4. Muri antene za televiziyo, zikoreshwa mu kuringaniza imbaraga z'amajwi hagati ya amplifiers na antene.
QualwaveItanga ibikoresho bitandukanye bipima neza kandi bifite imbaraga nyinshi bya coaxial 75 ohms bitwikira frequency ya DC ~ 3GHz, bishobora guhuzwa na BNC, F-type, na N-type connectors. Uburyo bwo kugabanya uburebure buri hagati ya 1 na 40dB. Ibikoresho bipima neza kandi bifite imbaraga nyinshi, ubwiza bwizewe, ibicuruzwa byinshi bikurikiza ROHS, bishobora guhaza ibyifuzo bitandukanye by'abakiriya.
