Rubutun BNC da SMA

Kewayyin RF, kamar yadda ake amfani da shi a cikin matsayin RF, suna daidai an yi amfani da shi ne kuma a cikin rubutu ba da alamannan. Shi ya gabata kewayyin kuriyar da idaka da aka samun wannan kewayyin, a ke samun gaskiya domin wannan kewayyin, domin ake samun gyara. Suna daidaiƙi na kewayyin RF. Yanar gaba, kuma zan iya buga wani farko canja BNC kewayyin da SMA kewayin.

 Tarihi
1) Kewayin BNC
Kunshi BNC ya same suna daidai na RF kunshi ake samu, ya same shi ne kunshi kewaye kawai ke nuna duniya. Sunan BNC ne Bayonet Nut Connector (kunshi kawaye, an yiwa rubutu mai wuce da wannan kunshi). Sunan asalihi na BNC (Bayonet Neill – Concelman) ya same bataƙi mai sabon masu Neill Paul na Concelman Carl, amma amma inaiyoyin N-type kunshi. Kunshi BNC suka samu a cikin takardun wireless, TV, alamna testin, da yadda RF alamunajia elektroniki. Takardun kompiyuta na wata suka samu kunshi BNC. Kunshi BNC ya samfuka bayan tunani 0 to 4GHz. An yiwa mai abubuwan zangon gaba: 50 ohms da 75 ohms.

2) SMA connector
Kwayankowa SMA ya ci gaba kwayankowa coaxial mai tsawo da kwayankonin thread-kaɗan, yayi suna cikakken wannan: bandar kari, performance mutum, reliability ga’anin, da dagaƙe aiki. Kwayankonon SMA su yana fitowar da RF cables ko microstrip lines a cikin RF circuits na alamannan microwave da systemin communication digital. Su ne kuma yanzu a cikin wireless devices don GPS clock interfaces a cikin single boards da testing ports a cikin modules RF na base station. Kwayankowa SMA ya fiye a 1960s. Bandar kari na signal dai dai da kwayankonon SMA yi shirya ta DC to 18GHz, da shi faruwa suka yi amfani da hanyar 26.5GHz. Impedance karakteristikai ne 50 ohms.

 Rubuce

1) Bandar kari different: Kwayankonon BNC su yana iya amfani da frequencies dai dai da 0 to 4GHz, while kwayankonon SMA su yana iya amfani da frequencies dai dai da 0 to 18GHz.

2) Amfani daidai: BNC ya ci gida kabiya na kafa cikin amfani daidai, ya same mutuwar shirye. SMA ya sama don amfani daidai na mikuroshe a cikin samarwa mai tsarin daidai, misali takalar rubutun mikuroshe.

3) Fadiffa na bayani daidai: BNC ya same amfani daidai da yanzu da karatse, mai tsarin bayanin daidai, sabon rayuwa, da amfani daidai da karatse, ya same amfani daidai da karatse daidai da karatse. SMA ya same bayanin daidai da shirye, amfani mai tsarin daidai, bayani mai tsarin daidai, da hanyar gabatar daidai.
