GORE® VNA Microwave RF Test Assemblies
Rugged, lightweight and highly flexible assemblies with construction that enable longer service life, reduced downtime and lower operating costs.
Guaranteed Stability for Precise, Repeatable Measurements
GORE® VNA Microwave/RF Test Assemblies are engineered for the most precise measurements in laboratory conditions. They deliver the highest accuracy and greatest time interval between recalibrations of any test assembly on the market. With proven high flexure, Gore’s assemblies maintain excellent insertion loss, VSWR and phase and amplitude stability.
Durable in Demanding Environments
We have engineered features for GORE VNA Microwave RF Test Assemblies that make them more rugged in demanding laboratory conditions, including:
- NMD-style ruggedized connectors
- crush resistance greater than 800 lbf/in
- over 50,000 flexures at minimum bend radius
- torque resistance
- virtually zero cable spring back
Improved Electrical & Mechanical Performance
GORE VNA Microwave RF Test Assemblies provide manufacturers with many benefits that improve electrical and mechanical performance, such as:
- extremely precise, repeatable measurements up to 70 GHz
- reliable, repeatable electrical performance with consistent phase and amplitude stability
- highest accuracy and greatest time interval between recalibrations
- easy installation with flexible construction and small bend radius
- decreased weight with smaller diameter for higher density applications
- design flexibility with a variety of interconnect options
Setting the Industry Standard through 70 GHz
GORE VNA Microwave RF Test Assemblies are engineered to perform reliably in a variety of test and measurement applications, including:
- vector network analyzers
- testing in lab environments
- critical measurements

Technical Information
Connector options include Precision N, 7 mm, 3.5 mm, 2.92 mm, 2.4 mm and 1.85 mm. NMD connectors available for GORE VNA Microwave RF Assemblies are specifically engineered to optimize the performance of each assembly. These connectors have an auxiliary, large thread and bearing surface for mating with conventional connectors of the same type and for attaching either male or female adapters.
The maximum operating frequency of a test assembly is determined as the lowest frequency of either the connector or the cable.

The pictures below illustrate an example of each connector type and description. The photos representing 3.5mm, 2.92mm, 2.4mm and 1.85mm connectors are of 3.5mm connectors; however, all connectors are of similar general appearance and will mate to analyzers and cables within the same connector family.
Selecting a Part Number
GORE 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: Two-letter code representing each cable type (e.g., FB, FD, FE and FF).
Positions 3–5: Connector A that will attach to the VNA. See below for the list of connectors available for each cable type.
Positions 6–8: Connector B that will attach to the device under test (DUT). See below for the list of connectors available for each cable type.
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-in test assembly is specified as 038.0 in the last four digits of the part number. Our assemblies are available in standard lengths of 25 in (0.64 m), 38 in (0.97 m) and 48 in (1.22 m).
If other assembly lengths are required, consider GORE® PHASEFLEX® Microwave RF Test Assemblies as an alternative.
