SMA connectors provide stainless performance
Stainless steel SMA connectors that meet or exceed the performance requirements of MIL-PRF-39012 are now available in Europe
Delivering superior performance up to 40GHz, for applications requiring high-frequency transmission, Johnson SMK 50ohm connectors are easy to install and replace in the field.
A selection of the SMK range is available with a hermetic seal - mounted into the circuit module wall - enabling connectors to be removed and replaced without destroying the hermeticity of the circuit housing.
Similar to a SMA interface, SMK connectors feature a smaller internal body diameter (2.92mm) and air dielectric to provide a higher cut-off frequency.

Type N connectors operate at frequencies up to 11GHz, with semirigid cable connectors and in-series adapters capable of operation up to 18GHz
The SMK plug interface employs more precise dimensions than an SMA and uses a shorter snub nose male pin, ensuring the connector bodies align before the contacts engage.
Precision manufacturing allows superior electrical performance up to 40GHz, and the SMK's female contacts have a unique, three-slot construction which enables connectivity by creating a more rugged device while reducing the chance of intermittent connections.
Featuring precise assembly tooling to ensure superior, repeatable contact and support bead location on cabled connectors, the range delivers connector mating interface per MIL-STD-348 and control for consistent electrical performance.
With a plug connector maximum VSWR of 1.20 to 40GHz, a 12in SMK plug-to-plug cable assembly performs above 1.35 VSWR to 40GHz.
