01 / CONFIGURATION DIRECTIONS

Select a configuration from the application boundaries

These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.

01

Types 04 / 65 / 6E

18 GHz families selected by loss, diameter and bend radius.

02

Type 6G

Compact 40 GHz airborne assembly.

03

Replaceable-connector assembly

Ends configured to equipment interface and maintenance strategy.

Match a solution direction to the link target

Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.

Technical referenceValues are confirmed against category, gauge, length and termination

03 / TYPICAL CONSTRUCTION

From functional core to terminated interface

LAYER 01

Silver-plated center conductor

Solid or stranded geometry is selected for frequency, power, flex and termination.

LAYER 02

Expanded PTFE dielectric

Maintains 50-ohm coaxial geometry while reducing high-frequency dielectric loss.

LAYER 03

Multilayer outer conductor

A stable return and shielding path limits impedance change after installation.

LAYER 04

Rugged or barrier jacket

Resists crush, abrasion, bending, vapor and aircraft-fluid ingress.

LAYER 05

Replaceable connector

Interface, direction, length and service strategy complete the assembly.
