The Johnson SMK Connector provides an excellent solution
for demanding applications requiring high frequency trans-
mission. Although similar to the SMA interface, a smaller
internal body diameter (2.92mm) and air dielectric provide
a higher cutoff frequency and other key advantages:
• Precision manufacturing allows superior electrical
• Female contacts have a unique three-slot construction,
• Precise assembly tooling assures excellent, repeatable contact and support bead location on cabled connectors.
• Connector mating interface per MIL-STD-348
• Mating interface control provides consistent electrical performance.
• The plug connector VSWR is 1.20 Max to 40 GHz and a 12 inch SMK plug to plug cable assembly performs
• The Field Replaceable Jacks are teamed with a high quality hermetic seal feed thru for use in sealed
• The SMK plug interface employs more precise dimensions than an SMA and uses a shorter snub nose male
* All gold plated parts include a .00005" min. nickel underplate barrier layer.
