75 ohms Attenuators 75Ω Kafaffen 75 Ohms Kafaffen
A 75 ohms attenuator wani nau'i ne na attenuator mai suna don impedance na 75 ohms.
Abu ne mai wucewa da ake amfani da shi don daidaita ƙarfin siginar da'ira, A 75Ω attenuator yana hana haɓakawa da jujjuya siginar, kuma yana hana gazawar da ke haifar da wuce gona da iri.
75Ω kafaffen attenuators manyan halaye sun haɗa da:
1. Bambancin daidaitawa: 75 Ohms Kafaffen Buttatoatatic Bala'i ya dace da halayyar watsawa na kayan bidiyon siginar sakonni, don haka tsarin talabijin na USB, don haka rage alama da asarar isar da isarwa.
2. Ƙananan murdiya: Mai kunnawa zai iya rage ƙarfin siginar ba tare da gabatar da ƙarin ɓarna ko tsangwama ba.
3. Babban AMINCI: Saboda gaskiyar cewa attenuators sun fi dacewa da sassa masu motsi kuma ba su da sassa masu motsi, suna da aminci sosai kuma ba sa buƙatar kulawa ko sauyawa.
75 ohms attenuators ana amfani da su a cikin aikace-aikacen masu zuwa:
1. A cikin cibiyoyin sadarwar telebijin na USB da kuma hanyoyin sadarwar talabijin na dijital, ana amfani da shi don daidaita ƙarfin sigina da rage alamar sigina da hasara.
2. A lokacin samarwa da watsa shirye-shiryen bidiyo masu mahimmanci da ma'ana, sarrafa ƙarfin siginar kuma kula da ingancin juyawa.
3. A cikin watsa shirye-shiryen watsa shirye-shiryen watsa shirye-shiryen siginar siginar talabijin, kayan aikin da ke daidaita ƙarfin sigina don daidaita ƙayyadaddun siginar da aka rarraba da kuma fadada kewayon sigina.
4. A cikin eriya ta talabijin, ana amfani da ita don daidaita ƙarfin sigina tsakanin amplifiers da eriya.
Qualwaveyana ba da madaidaicin madaidaici daban-daban da babban ƙarfin coaxial 75 ohms attenuators suna rufe kewayon mitar DC ~ 3GHz, ana iya daidaita su tare da masu haɗa nau'in BNC, F-type, da N-type. Attenuation ne yafi jeri daga 1 zuwa 40dB. Masu haɓakawa tare da Babban madaidaici da babban iko, ingantaccen inganci, yawancin samfuran suna bin ROHS, na iya biyan bukatun abokan ciniki daban-daban.
