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 highperformance 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.
Key Features |
Extremely precise measurements with stable electrical performance up to 70 GHz |
Outstanding phase and amplitude stability with flexure |
Excellent reliability with extremely rugged cable construction and NMD-style connectors that withstand repetitive mating, flexure, crushing, twisting, and bending |
Reduced downtime because of increased intervals between calibrations |
Typical Applications |
Vector network analyzers |
Testing in lab environments |
Critical measurements |
VNA Microwave/RF Test Assemblies are identified by a 12-character part number that designates the cable type, connector types, and assembly length.
Positions 1 - 2: The two-letter codes representing each cable type. (eg FB, FD etc)
Position 3 - 5: Connector that will attach to the VNA (See; Connector A (End A, VNA¹) table)
Position 6 - 8: Connector that will attach to the device under test (DUT)
Positions 9–12: The length of the assembly expressed in inches to the nearest tenth, including zeroes to fill positions if the length is less than three digits.
(For example, the length of a 38-inch test assembly is specified as 038.0 in the last four digits of the part number. Cables are available in standard lengths of 25 in (0.64 m), 38 in (0.97 m) and 48 in (1.22 m)).
