RF Imbaraga Zinini BroadBand Sisitemu Yibizamini 75 ohms Attenuator
75 ohm attenuator ni ubwoko bwa attenuator yitiriwe impedance ya 75 oms.
Nibintu byigenga bikoreshwa mugutunganya imbaraga zumurongo wumuzunguruko, A 75 ohm attenuator irinda kwaguka gukabije no kugoreka ibimenyetso, kandi ikarinda kunanirwa guterwa nikimenyetso kirenze urugero.
Ibintu nyamukuru biranga harimo:
1. Guhuza impedance: 75 ohm iranga impedance ihuye nimbogamizi iranga umurongo wohereza ibimenyetso byibikoresho bya videwo, tereviziyo ya tereviziyo na televiziyo ya kabili, bityo bikagabanya gutekereza no gutakaza ibimenyetso byohereza.
2. Kugoreka gake: Attenuator irashobora kugabanya imbaraga zikimenyetso itabanje kugoreka cyangwa kubangamira ibimenyetso.
3. Kwizerwa cyane: Bitewe nuko attenuator ahanini igizwe nibintu byoroshye kandi bidafite ibice byimuka, birizewe cyane kandi ntibisaba kubitaho cyangwa kubisimbuza.
75 ohm attenuator ikoreshwa mubisanzwe bikurikira:
1. Mu miyoboro ya tereviziyo ya kabili hamwe na tereviziyo ya tereviziyo ya digitale, ikoreshwa mu kugenzura imbaraga zerekana ibimenyetso no kugabanya ibimenyetso byerekana no gutakaza.
2. Mugihe cyo gukora no guhererekanya amashusho menshi kandi asobanutse neza, genzura imbaraga zikimenyetso kandi ukomeze ireme ryiza.
3. Muri sisitemu yo gukwirakwiza ibimenyetso na tereviziyo, ibikoresho bihindura imbaraga zerekana ibimenyetso kugirango bihuze uburyo bwo gukwirakwiza ibimenyetso no kwagura ibimenyetso.
4. Muri antene ya tereviziyo, ikoreshwa mu kuringaniza imbaraga zerekana ibimenyetso hagati ya amplifier na antene.
Qualwaveitanga ibintu byinshi bihanitse kandi bifite imbaraga nyinshi coaxial 75 ohms attenuator itwikiriye intera ya DC ~ 3GHz, irashobora guhuzwa na BNC, F-F, na N-ihuza.Kwiyegereza cyane cyane kuva kuri 1 kugeza 30dB.Ibyiyumvo bifite ibisobanuro bihanitse kandi bifite imbaraga nyinshi, ubuziranenge bwizewe, ibicuruzwa byinshi byujuje ROHS, birashobora guhaza ibyifuzo bitandukanye byabakiriya.
