High-frequency SMA connectors

29 April 2009 Interconnection

Vitelec has released a 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 range is suitable for a variety of applications including GPS antennas, wireless infrastructure antennas, radar systems and high-speed routers and switches.

The connectors are specifically targeted at engineers designing circuits 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 26,5 GHz.

Eliminating the requirement for external mounting screws, adaptor 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 planes, 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.
