W.L. Gore & Associates has introduced a new low-profile right-angle connector (ZQA) that features a non-bifurcated swept contact design for use with low-loss microwave coaxial cable qualified for 32 GHz spaceflight applications.
Traditional box right-angle connectors are often associated with poor VSWR (voltage standing wave ratio) performance, particularly at frequencies approaching 18 GHz. This is because many box right-angle designs employ a bifurcated (two-part) internal contact. While the bifurcated configuration allows for easy assembly and low cost, its shape does not lend itself to good internal impedance control or to a robust solder connection.
Gore’s ZQA connector incorporates the physical advantages of the box right-angle designs – i.e., low profile and compact size – while at the same time maintaining electrical performance comparable with conventional straight connectors. Gore replaced the two-piece bifurcated concept with an internal swept right-angle configuration. The ZQA provides a more robust design with superior impedance control, maintaining a low reflection path as the signal transitions from cable through connector.
As a 2.92 mm instrument grade connector, the ZQA adheres to IEEE 287 standards for precision coaxial connectors with respect to inner conductor, outer conductor, and contact height dimensions. As with other instrument grade connectors, the ZQA uses dielectric support at its interface, making the ZQA extremely durable while still providing excellent overall electrical performance and intermateability with SMA, 3.5 mm, and 2.92 mm air interface connector types without concern of adverse electrical or mechanical effects.
