Pasternack debuts a line of flexible precision VNA test cables rated to 50 and 67GHz depending on the series. Designed for use as VNA test port extenders, these highly durable and flexible test cables are able to withstand the rigors of test lab use where these cables are constantly flexed during common testing situations.

Pasternack’s lines of highly flexible VNA test cables have excellent electrical properties including low VSWR of 1.3:1 at 50GHz and 1.4:1 at 67GHz as well as superb phase stability with flexure of +/- 6° at 50GHz with the 2.4mm connectors and +/- 8° at 67GHz using 1.85mm connectors. The braided stainless steel armoring surrounding the coax provides a rugged, but flexible cable with a flex life exceeding 100,000 cycles.

The rugged stainless steel 2.4 and 1.85mm connectors provide up to 5,000 mating cycles when attached with proper care. Additionally, the flexibility of these cables makes it easier and safer to test a Device Under Test (DUT). A swept right angle connector option allows these cables to fit in tight spaces and can reduce the length of cable required in many applications.

Some of the most common applications benefiting from Pasternack’s flexible test cables include use as VNA test port extenders, semiconductor probe testing, precise bench top testing and lab/production testing where the need for a highly flexible, yet durable cable solution is required.

“Our offering of off-the-shelf flexible VNA test cables rated to 50 and 67GHz are a very unique and in-demand cable solution that are not traditionally available as a stocked item,” explains Steve Ellis, Interconnect Product Manager, Pasternack. “These test cables also boast industry-leading right angle connectors and electrical performance that provide engineers with the perfect solutions for their high frequency testing applications.”
