GORE-FLIGHT™ micro wa ve assemblies Lightweight solution with lowest insertion loss before and after installation Airframe cable assemblies are exposed to extreme conditions that can compromise their performance — beginning with the challenges of installation and continuing through the rigorous flight conditions that combine rapid temperature and pressure changes with potential contamination from fuels, oils, and fluids. Maintaining signal integrity in these challenging environments is essential to ensuring the reliability of the sophisticated electronic systems in the aircraft. At the same time, the assemblies must be lightweight and durable to improve fuel efficiency and reduce operating costs. 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 (Table 1). 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. The 6 Series has been qualified to the most stringent specifications for airframe assemblies. Gore controls the entire manufacturing process from purchasing raw materials and creating and applying the proprietary dielectric material, through testing and shipping the final cable assembly. This unsurpassed vertical integration allows Gore the complete control necessary to achieve tight specifications consistently. This process includes testing 100 percent of the assemblies for vapor leakage, dielectric withstanding voltage, VSWR, insertion loss, impedance, and velocity of propagation — ensuring that every assembly will deliver the highest-quality performance required for today’s civil and military aircraft. Typical Applications • Airborne electronic surveillance/counter measures • Radar warning (electronic defense) systems • Missile approach warning systems • Radar interconnects • Electronic/signal intelligence • Navigation/communication systems Benefits of GORE-FLIGHT™ Microwave Assemblies, 6 Series • Outstanding signal integrity with lowest insertion loss before and after installation • Lower installation costs due to fewer failures and reduced aircraft production delays • Improved fuel efficiency and increased payload with lightweight assembly • Longer system life and reduced downtime due to mechanically robust construction • Less RF interference among electronic systems due to superior shielding effectiveness • Proven compliance with MIL-T-81490 requirements3 a See Table 2 for specific compliance data

MICROWAVE ASSEMBLIES Rugged Construction for Longer Service Life Figure 2: Shake Stability b,c GORE-FLIGHT Microwave Assemblies, 6 Series are engineered with a rugged construction that withstands the challenging environments they encounter throughout an aircraft’s service life (Figure 1). The engineered fluoropolymers used in this construction help reduce abrasion caused by routing during installation, and they help maintain stable performance by resisting the effects of vibration during flight (Figure 2). ™ With a concentrated load resistance that exceeds MilSpec requirements, the 6 Series...

GORE-FLIGHT. microwave assemblies Proven Performance Through Testing Gore has designed a simulator to evaluate the stress of installation on microwave airframe assemblies (Figure 4). The simulator has several features that replicate minimum bend radius conditions, routing guides that induce torque, and an abrasive edge to simulate routing across sharp edges or through access holes in the airframe structure (Figure 5). The simulator enables Gore to evaluate the electrical performance of various cable assemblies after installation. Testing electrical characteristics such as insertion loss and...

Excellent Signal Integrity for Improved Reliability GORE-FLIGHT™ Microwave Assemblies, 6 Series improve system performance by withstanding the challenges of installation, maintenance activities, and flight conditions. When compared to alternative airframe assemblies (Figure 6), the 6 Series maintains the lowest insertion loss before and after installation (Figure 7) — providing stable and accurate system performance. Likewise, the VSWR of alternative airframe assemblies is less reliable due to impedance changes from cable damage (Figure 8), while the VSWR for the 6 Series is well controlled...

Ordering Information GORE-FLIGHT™ Microwave Assemblies are identified by a 12-character part number. This number designates the cable type, connector types, and assembly length: if the length is less than three digits. For example, the length of a 24.0-inch assembly is specified as 0240 in the last four digits of the part number.
