SMA (SubMiniature version A) connector shine ake amfani sosai da yawa, kuma shine RF connector na microwave da high-frequency systems. Ya kashe thread na ƙaramin kwayoyin (1/4-36 UNS), kuma ya dace don samun ƙirar da kyau daga DC zuwa 18 GHz, kuma wani ƙaramin kwayoyin ya dace zuwa 26.5 GHz. Karamin sa da tsayin sa na kyau suka saita shi don zama abin da aka so sosai a telecommunications na zamanin yanzu da applications na PCB.
Manyan siffofi & Binciken
- Karamin Kyauta na High-Frequency: An rufe SMA connectors don microwave applications, suna gudanar da low VSWR da karamin signal loss a cikin frequency spectrum mai yawa (DC zuwa 18/26.5 GHz).
