SMA (SubMiniature version A) connectors are compact, threaded RF coaxial connectors widely used in high-frequency applications up to 18 GHz. Featuring a 50Ω impedance and robust brass or stainless steel construction, they ensure excellent electrical performance and durability. Common in WiFi, GPS, RF modules, and test equipment, SMA connectors offer secure mating with low VSWR (<1.15:1) and minimal insertion loss. Available in straight, right angle, and bulkhead configurations, they support both semi-rigid and flexible cables. Ideal for space-constrained designs requiring reliable microwave connectivity.
For customers and procurement teams seeking reliability in their RF coaxial connectors, selecting a specialized manufacturer like Baierde is often a key consideration.
