The default altitude of 0’, which is changeable by the user, is used for power handling de-rating of the cable, if required.
This style has two angled connectors that are terminated directly to the cable.
- Angled (Replaceable End)
This style has two replaceable angled connectors that are mounted to intermediate adapters.
A series cable assemblies are actually “armored” against physical abuse. This type of ruggedization offers a high level of protection, at the sacrifice of size and weight.
Armored ruggedization consists of stainless steel flexible conduit, which can withstand 800 pounds of compression force per linear inch. Additionally, cable bend radius is physically limited, but flexibility is retained.
Armored assemblies are used for applications where severe cable pinching or crushing is likely, and for applications which require an automatic limitation of bend radius.
- Center Conductor
GORE® Microwave/RF Assemblies are available with either solid or stranded center conductor designs.
Solid center conductor configurations provide low-loss, but are not well suited in applications where repeated flexing (hand or mechanized) of the cable occurs, especially at tight bend radii.
Stranded center conductor configurations are ideal for flex applications as GORE’s stranded cable designs and its use of materials result in strength and flexibility.
GORE® has the following connector styles available. For the available types (e.g. SMA, TNCA, etc.) please contact GORE®.
Straight – this is a straight connector that is terminated directly onto the cable at each end.
Straight (Replaceable End) – this is a straight connector that is mounted onto an intermediate adapter at each end. The connector is removable and replaceable in the event it is damaged during integration without a change in assembly performance.
Straight/Angled – this style has a straight at one end and an angled connector at the opposite end.
Straight/Angled (Replaceable End) – this style has replaceable ends mounted to intermediate adapters at each end. One end has a straight replaceable connector, the other end has an angled replaceable connector.
Angled – this style has two angled connectors that are terminated directly to the cable.
Angle (Replaceable End) – this style has two replaceable angled connectors that are mounted to intermediate adapters.
- Electrical Length in Degrees/Nanoseconds
This represents the estimated electrical length of the assembly without consideration of connectors. In most cases the actual electrical lengths will be slightly greater than this estimate.
- General Purpose
General purpose cable type. Size for size, GORE® Microwave/RF Assemblies provide low insertion loss cable assemblies. This is accomplished through a unique cable design that exploits the low dielectric constant, low loss tangent, and conforming nature of expanded polytetrafluoroethylene (ePTFE) dielectric.
- Insertion Loss
Insertion Loss is the amount of signal (in dB) lost when it is transmitted through an assembly.
- Network Analyzer
GORE® VNA Microwave/RF Test Assemblies set the industry standard for vector network analyzers (VNAs) through 67 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.
- Power handling
Calculated in Watts CW. All power values represent a value derated by 50% for safety purposes at ambient (temperature and altitude) default conditions. If the temperature and altitude are changed, a GORE® derated figure for these conditions is calculated. These power handling numbers are meant to provide a guide for cable power. To consider the entire cable assembly and other considerations (e.g. multipaction), please consult with a GORE® representative.
- Return Loss
Return loss is the loss of signal power resulting from the reflection caused at a discontinuity in a transmission line.
- Ruggedized and Phase Stable
GORE® PHASEFLEX® Microwave/RF Test Assemblies are internally ruggedized with excellent phase and amplitude stability. With the ruggedization designed into the cable, the assemblies have excellent durability while remaining exceptionally lightweight and flexible.
GORE® Microwave Sealed Airframe Assemblies (7-Series) is vapor sealed to prevent the ingress of water vapor, jet fuel, and other solvents. This ensures that GORE's 7-Series maintain insertion loss and phase performance over the entire life cycle. These Assemblies meet or exceed the mechanical and environmental environments for airframe cables defined in MIL-T-81490.
- Sealed and Ruggedized
GORE-FLIGHT™ Microwave Assemblies, 0 series utilize an internally ruggedized construction that withstands concentrated loads well in excess of those specified by MIL-T-81490, reducing the likelihood of inadvertent crush damage during installation and throughout service life. The flexibility of the assembly, coupled with an inherent resistance to over bending, provides a cable assembly that is easier to install within the confines of an aircraft. Vapor and liquid barriers prevent any ingress of oils, fuels, coolants or cleaning fluids, ensuring continued electrical performance even in the harshest of environments. These assemblies have been qualified to the most stringent specifications for airframe assemblies.
- Sealed, Ruggedized, Lightweight
GORE-FLIGHT™ Microwave Assemblies, 6 Series are lightweight cable solutions that deliver the lowest insertion loss before and after installation, ensuring reliable performance for the life of the system. The robust construction of these assemblies reduces total costs by withstanding the challenges of installation, reducing costly production delays, field service frequency, and the need for purchasing replacement assemblies. Also, the 6 Series are lighter weight, which improves fuel efficiency and increases payload. Vapor and liquid barriers prevent any ingress of oils, fuels, coolants or cleaning fluids, ensuring continued electrical performance even in the harshest of environments.

The default temperature of 25° C, which is changeable by the user, is used for both insertion loss change over temperature as well as power handling de-rating of the cable, if required.
Voltage Standing Wave Ratio. It is a measure of how efficiently radio-frequency power is transmitted from a power source, through a transmission line, into a load.
