CC-SA is a 50 ohm male SMA plug. The hex-head design fits a 5/16 inch
(8 mm) wrench.
The center pin solders onto the core wire, providing a low-noise
electrical connection. The outer crimp ferrule is sized for the shield
and jacket of an RG174, RG316, or similar-size coaxial cable --
the maximum cable size which will fit this connector is about 3mm
diameter. Cables with a diameter smaller than 2mm will need heatshrink
added around the jacket to add to their diameter and make a secure
mechanical connection when crimped.
One of the most common RF and microwave connectors, SMA connectors are
often used in RADAR, ham radio base stations, avionics, and other
permanent installations. Designed for a few hundred
connect/disconnect cycles, they are intended for use in applications
which require infrequent disconnection.
SMA connectors are usable
at high frequencies; around 12.4 GHz, or as high as 18-24 GHz under
ideal conditions. Their design removes air gaps during mating,
providing high voltage capacity, an advantage in high-power radio or
SMA stands for "SubMiniature version A"; this family of connectors was
originally designed by Bendix in the 1960's, and is described in
This connector has a characteristic
impedance of 50 ohms, and needs to be mated with
50 ohm coaxial cable in order to prevent signal loss, noise,
and/or transmitter damage due to signal reflections at the point of
50 ohm coax cable, connectors, and adapters are commonly used in GPS
and wifi (802.11 wireless LAN) antennas, ham transceivers, and other
radio frequency (RF) analog and digital signaling, microwave, radar,
hi-fidelity professional audio, non-destructive testing (NDT), oil and
petroleum production, ultrasonic transducers, accelerometers, strain
gauges, and some professional video applications.
