Compression-mount connector supports up to 50GHz

Featuring a stub-less design with screw-mounting to the PCB, the high-bandwidth coaxial connector simplifies the assembly process and provides several electrical and mechanical advantages over soldered versions. With traditional soldered through-hole type models, signal reflection may be caused by the stub protruding through the board, but with the H2.4 compression-mounted connector, the centre contact is mounted flush with the PCB. This eliminates the stub, and signal reflection is significantly reduced. The connector also optimises design flexibility as it can be used with PCB boards of various thicknesses (1.6mm minimum). In addition, the device is reusable and can be attached and removed to boards for multiple uses, saving time and costs.

"Solder terminations inherently introduce the potential for human error. A screw mount design eliminates this human error variable and ensures a high reliability connector with excellent high- frequency performance and consistent assembly quality," said Rick van Weezel, Vice-President, Sales and Marketing, Hirose Electric USA. "Through-hole mount types are also limited to one PCB thickness, but a stubless screw mount type allows for various PCB thickness with one connector type."

The H2.4 plug is manufactured with a 0.085” semi-flexible cable with terminated plugs on each end, and the receptacle features a gold-plated ground ring for stabilising grounding on the PCB.

The connector has a maximum contact resistance of 4mΩ in the centre and 2mΩ in the outer section. This H2.4 coaxial connector is rated for 500 mating cycles with a characteristic impedance of 50Ω.
