Bambanci tsakanin masu haɗin BNC da masu haɗin SMA

Masu haɗin RF, kuma aka sani da masu haɗin RF, yawanci ana ɗaukarsu azaman abubuwan da aka sanya akan igiyoyi ko kayan aiki. Suna aiki azaman haɗin lantarki ko abubuwan rabuwa don layin watsawa, galibi suna aiki azaman gadoji. Akwai nau'ikan masu haɗin RF da yawa. A yau, bari mu kalli bambance-bambance tsakanin masu haɗin BNC da masu haɗin SMA.

1) mai haɗin BNC
Haɗin BNC kuma ɗayan masu haɗin RF ne da ake gani da yawa, wanda ƙaramar mai haɗawa ce wacce zata iya samun haɗin kai cikin sauri. Cikakken sunan BNC shine Haɗin Bayonet Nut (mai haɗa mai dacewa, wanda ke bayyana bayyanar wannan mai haɗawa a sarari). Asalin ma'anar BNC (Bayonet Neill - Concelman) a zahiri ta fito ne daga haruffan farko na sunayen sunayen Paul Neill da Carl Concelman, waɗanda suma suka ƙirƙiro mai haɗin nau'in N. Ana amfani da masu haɗin BNC sosai a tsarin sadarwar mara waya, talabijin, kayan gwaji, da sauran na'urorin lantarki na RF. Hanyoyin sadarwar kwamfuta na farko kuma sun yi amfani da masu haɗin BNC. Mai haɗin BNC yana goyan bayan kewayon mitar sigina na 0 zuwa 4GHz. Akwai nau'i biyu na halayen halayen halayen: 50 ohms da 75 ohms.

2) SMA connector
Mai haɗin SMA shine mai haɗin haɗin haɗin gwiwa da aka yi amfani da shi sosai tare da ƙananan haɗin zaren, wanda ke da halaye na bandeji mai faɗi, kyakkyawan aiki, babban aminci, da tsawon rayuwar sabis. Masu haɗin SMA sun dace don haɗa igiyoyin RF ko layin microstrip a cikin da'irar RF na na'urorin microwave da tsarin sadarwar dijital. Ana amfani da su akai-akai akan na'urori mara waya don mu'amalar agogon GPS akan alluna ɗaya da tashoshin gwaji don samfuran RF na tushe. An ƙirƙira mai haɗin SMA a cikin 1960s. Kewayon mitar siginar da masu haɗin SMA ke goyan bayan ya tashi daga DC zuwa 18GHz, kuma wasu nau'ikan na iya tallafawa har zuwa 26.5GHz. Halayen impedance shine 50 ohms.

 Sauyi

1) Matsakaicin mitoci daban-daban: Masu haɗin BNC sun dace da mitoci daga 0 zuwa 4GHz, yayin da masu haɗin SMA suka dace da mitoci daga 0 zuwa 18GHz.

2) Amfani daban-daban: BNC shine mai haɗin kebul na coaxial maras ƙarfi tare da hanyar haɗin bayoneti. SMA ya dace da aikace-aikacen microwave wanda ke buƙatar babban aiki, kamar haɗin ciki na kayan aikin microwave.

3) Abũbuwan amfãni sun bambanta: BNC na iya haɗawa da sauri da kuma rabuwa, tare da halaye irin su haɗin kai mai dogara, kyakkyawar juriya mai kyau, da haɗin kai da kuma rabuwa mai dacewa, yana sa ya dace da haɗin kai akai-akai da yanayin rabuwa. SMA yana da halaye na ƙananan girman, ingantaccen aiki, babban abin dogaro, da tsawon rayuwar sabis.
