8.5GHz connectors go straight to the PCB

Powell Electronics has announced that will be stocking a second generation of GDBC (Gigalane direct board contact) one-piece contacts from Gigalane.

The “contacts are easy to use in the assembly as they require no SMT”, said Powell.

Instead, the connector is installed in the face of an assembly, and then pushed face-down onto the PCB to make coaxial contact – the claws in the images are the outer pcb contact, for example.

Axial tolerance when mated is ±0.5mm – nominal max mating force is 1.4kg (0.8kg at +0.3mm and 2kg at -0.3mm). Max radial landing tolerance is ±0.5mm.

Powell said frequency coverage of the 50Ω contacts is dc to 8.5GHz, with a VSWR range of 1.12:1 (3GHz), 1.22:1 (6GHz) and 1.35:1 (8.5GHz).

Insulation resistance is 5GΩ and they offer 750Vrms dielectric withstand.
