VNA upgrade meets 60GHz-70GHz requirements

Article By : Gore

Gore claims that its 70GHz assemblies have a rugged, lightweight construction that extends service life, reduces downtime and lowers operating costs.

W. L. Gore & Associates Inc. has expanded its FF Series Gore VNA Microwave/RF Tests Assemblies to offer up to 70GHz performance. Gore said that the upgrade addresses industry requirements for enhanced performance in the 60GHz-70GHz range.

Constant and/or highly repetitive movement of cables can compromise the measurement precision of high-performance VNAs. "Gore VNA Microwave/RF Test Assemblies are engineered to provide the most precise VNA measurements under laboratory conditions, delivering the highest accuracy and the greatest time interval between recalibrations," said Chris Cox, Gore Product Specialist, Electrical Cable & Components, in a press statement.

The test assemblies maintain insertion loss and VSWR. Gore noted that their assemblies ensure accurate and repeatable measurements because of their phase and amplitude stability with flexure. Prior to shipment, the assemblies are tested for return loss, insertion loss, phase stability, and loss stability up to their maximum operating frequency, the company added.

The assemblies are constructed with an abrasion-resistant polymer braid around a flexible armor casing. They withstand crush forces of more than 800pounds force/inch and have an auto-limiting bend radius of 57.2mm.

Gore VNA Microwave/RF Test Assemblies include NMD-style ruggedised connectors for direct attachment to VNA test ports and allow the use of test portcompatible adapter. The combination of the assembly’s ruggedised construction and NMD-style connector extends the flex life with consistent performance and reduced frequency of recalibration, Gore said.
