Pasternack has introduced a range of flexible precision VNA test cables rated to 50 and 67 GHz depending on the series.

Designed for use as VNA test port extenders, the 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 flexible VNA test cables claim excellent electrical properties including low VSWR of 1.3:1 at 50 GHz and 1.4:1 at 67 GHz as well as superb phase stability with flexure of +/- 6° at 50 GHz with the 2.4 mm connectors and +/- 8° at 67 GHz using 1.85 mm 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 mm and 1.85 mm 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 new 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.
