TEST ASSEMBLIES Improved VNA performance with precise measurements GORE® VNA Microwave/RF Test Assemblies set the industry standard for vector network analyzers (VNAs) through 70 GHz. Constant and/or highly repetitive movement of cables can compromise the measurement precision of high-performance VNAs. Leading manufacturers choose GORE® VNA Microwave/RF Test Assemblies because of the improved performance they see in their equipment. These test assemblies are specifically engineered to provide the most precise VNA measurements under laboratory conditions. They deliver the highest accuracy and the greatest time interval between recalibrations. GORE® VNA Microwave/RF Test Assemblies have a rugged, lightweight construction that enables longer service life, reduced downtime, and lower operating costs over the life of the equipment. Typical Applications Benefits of GORE® VNA Microwave/RF Test Assemblies •• Vector network analyzers •• Testing in lab environments •• Critical measurements •• Extremely precise measurements with stable electrical performance up to 70 GHz Guaranteed Stability for Precise and Repeatable Measurements •• Outstanding phase and amplitude stability with flexure GORE® VNA Microwave/RF Test Assemblies maintain excellent insertion loss and VSWR (Figure 1). Unlike conventionally designed RF test assemblies, Gore’s assemblies ensure accurate and repeatable •• Excellent reliability with extremely rugged cable construction and NMD-style connectors that withstand repetitive mating, flexure, crushing, twisting, and bending Figure 1: Typical VSWR Performance1 •• Reduced downtime because of increased intervals between calibrations measurements because of their excellent phase and amplitude stability with flexure (Figures 2 and 3). Additional testing is performed to guarantee this performance with flexure. See Table 1 for typical and guaranteed performance for each assembly. 1 Data is based on Gore’s 50 GHz VNA assembly FE0BN0BM025.0. Prior to shipment, all GORE® VNA Microwave/RF Test Assemblies are tested for return loss, insertion loss, phase stability, and loss stability up to their maximum operating frequency. Gore test methods simulate real-world environments to ensure that the assembly delivers precise and repeatab

Durable and Rugged Construction GORE VNA Microwave/RF Test Assemblies offer outstanding electrical and mechanical performance for extremely precise and repeatable measurements (see Table 1 for product specifications). ® Constructed with an abrasion-resistant polymer braid around a flexible armor casing, these assemblies are extremely durable (Figure 4). They withstand crush forces of more than 800 pounds force/inch and have an auto-limiting bend radius of 2.25 in (57.2 mm). Even with this armored and rugged construction, GORE® VNA Microwave/RF Test Assemblies maintain excellent flexibility,...

Ordering Information Ordering GORE® VNA Microwave RF/Test Assemblies requires selecting the cable type, connector types and assembly length, which are identified by a 12-character part number: Connector A Connector B Assembly Length Positions 1-2: See Table 1 for the two-letter codes representing each cable type. Positions 3-5: Connector that will attach to the VNA; see Table 2 for the list of connectors available for each cable type. Positions 6-8: Connector that will attach to the device under test (DUT); see Table 3 for the list of connectors available for each cable type. Positions...
