VNA test cables supporting frequencies up to 70GHz

Pasternack has launched a new line of highly flexible Vector Network Analyser (VNA) test cables designed to address a wide range of demanding lab and test applications. The new VNA test cables display excellent electrical properties such as phase stability of +/- 6° at 50GHz and +/- 8° at 70GHz with flexure, as well as VSWR of 1.3:1 at 50 GHz and 1.4:1 at 70GHz.

The new 50GHz assemblies are terminated with 2.4mm connectors, while the 70GHz assemblies utilise 1.85mm connectors. The braided, stainless steel armoring surrounding the coax provides a rugged yet flexible cable with a flex life exceeding 100,000 cycles, making these test cables ideal for use in precise bench top testing, semiconductor probe testing, and lab/production testing where the requirement for a durable, yet highly flexible cable solution is a must.

These new VNA test cables are terminated with rugged, stainless-steel connectors that provide up to 5,000 mating cycles when attached with proper care. Both 50GHz and 70GHz versions are offered with NMD-style connectors which are often used on test sets and network analysers. Additionally, the flexibility of these cables makes it easier and safer to test a Device Under Test (DUT). Swept right-angle 2.4mm and 1.85mm connector options allow these cables to fit into tight spaces and reduce the length of cable which is required in many applications.

“These new VNA test cables not only offer performance up to 70GHz, but they can also withstand 100,000 flexure cycles while still exhibiting excellent phase stability and amplitude to the given frequency. Furthermore, these assemblies are all in-stock to address our customers’ urgent product needs,” said Steve Ellis, Product Line Manager.

Pasternack’s high flexibility VNA test cables are in-stock and available for immediate shipping with no minimum order quantity (MOQ) required.
