SMA Male Plug RG58/RG58U Coaxial Connector Nickel Plated Body Gold Centre PinThe Gold centre pin should be soldered and the barrel crimped. Our crimp tools: C.513 & HT.336G are designed for RG174 coaxial connectors. Antenna ConnectorSMA connectors are semi-precision, subminiature connectors that provide repeatable electrical performance from DC to 12.4 GHz with flexible cable. Semi-rigid cabling extends the frequency range to 18 GHz. SMA connectors offer brodband performance with low reflection and constant 50 ohm impedance. These features, along with miniumum attenuation and low VSWR have made the SMA extremely popular in the microwave community. The SMA design has been broadened to accommodate many interconnection requirements and it"s design parameters have incorparated the considerations of cost, size, weight and performance to yield the best value in your microwave system. Typical applications include Mobile Data Terminals, Telemetry and M2M applications.
