 SMA / RP-SMA Connectors
 SMA connector is a type of RF connector developed in the 1960s to make it easier to coaxial cables.SMA's
 compact design, high durability and outstanding electronic performance have made it one of the most widely 
 used connectors in RF and Microwave applications across the board. Normally utilized in frequency ranges
 from DC-18GHz, there are also precision versions that can reach as high as 26.5GHz .
 
 SMA connector is available both in Standard and Reverse Polarity. where the male and female interface is   s
 witched. Regarding to extensive small scale coaxial which join whorl that has a reliable characteristic with long 
 life-span that the width, performance are excellent, high frequently. Suitable for the microwave equipmentand
 body of the digital communication system and join in the cable for the microstrip line frequency in the loop
 frequently.
