Microwave connectors come to Europe

An Emerson Network Power - Vitelec Electronics product story

Johnson has released its advanced range of high-frequency SMA end launch connectors in Europe.

Johnson, part of Emerson Network Power Connectivity Solutions, has announced the European release of its advanced range of high-frequency SMA end launch connectors.

Specifically designed for the transition of microwave energy from coaxial to planar transmission line structures, the low-profile and cost-effective range is perfect for a wide variety of applications including GPS antennas, wireless infrastructure antennas, radar systems and high-speed routers and switches.

Available throughout Europe from Vitelec Electronics and its authorised distribution network, these patent-pending connectors provide a unique solution for microwave engineers fabricating circuit designs on very thin, high-frequency board substrates.

The inline connector design minimises reflections in comparison to a right angle PC mount transition and allows operation at frequencies up to 26.5GHz.

Eliminating the requirement for external mounting screws, adapter sections or spring clips for assembly to the circuit board, the connectors incorporate a number of features that differentiate the range from other launch connectors.

The centre contact pin does not require special orientation to the surface of the circuit board - it is mechanically captivated and maintains proper impedance while withstanding torque and axial forces.

Output coax of the connector at board launch is appropriately sized to match the thickness of the high-frequency board substrate, while the launch transition is effectively isolated from adjacent transmission lines in the signal plane.

As a result, no additional shielding is required to prevent signal cross-talk effects in the transition area.

When placed on a circuit board, the connectors' floating design allows alignment in x, y and z, minimising discontinuities due to manufacturing tolerances.

A small amount of PTFE insulation projects from the rear mating plane of the connector, creating a barrier to prevent the bridging of solder between inner and outer conductors.
