Cannon 50 Ohm Connectors COMMERCIAL SMAHeading_1
Cannon’s Commercial SMA connectors are subminiature
devices that provide repeatable electrical performance
through the frequency range DC to 18.0 GHz. These 50
ohm connectors offer minimum attenuation with low
reflection which makes them extremely popular in the
R
F and microwave industry. The MIL-C -39012 series
SMA interface ensures they can be mated with all
connectors meeting the MIL specification dimensions.
They are designed for use with a variety of subminiature
coaxial cables. This includes semi-rigid and hand
formable cables as well as the popular RG series of
flexible cable and commercial cables meeting these
dimensions.
These SMA connectors feature stand-off legs on the PCB
mount designs to enhance soldering, cleaning and
inspection. The straight plugs feature crimp / solder
contacts for speed of assembly and high performance.
SMA connectors are found in many diverse applications
including amplifiers, dividers, filters and attenuators.
The standard units are supplied in gold plate. Nickel
plated versions are available on request.
