How to balance the size and material of RF cables and connectors for avionics?(1

Radio frequency (RF) technology used in military and commercial avionics applications prioritizes weight reduction to improve fuel efficiency while meeting strict electrical and mechanical safety requirements. Low loss, phase stability, and high performance in shock and vibration environments require careful evaluation of materials, structure, and maintenance to balance downsizing.

Today’s complex frequency band requirements--including 5G, new and upgraded satellite communications (SATCOM) systems, instrument flight procedures (IFP) systems using Bluetooth, etc.--are creating additional light, small, high-precision radio frequency (RF) ) The demand for the solution.

In some cases, these systems operate at frequencies up to 90 GHz. The avionics industry needs low-loss, high-temperature-resistant, and highly flexible cables for navigation, collision avoidance, and communication system communications in GPS, automatic dependent surveillance broadcasting (ADS-B), satellite communications, and air-to-ground applications.

The space for avionics applications is also limited, because they have to adapt to more application requirements in the entire device. As frequencies increase and interconnect sizes decrease to accommodate smaller wavelengths, semi-rigid solutions have traditionally been used for these applications. However, these very small components become fragile, making installation difficult and impossible to troubleshoot.

The use of highly flexible, high-performance cables can be used for densely packed open-box applications; this flexible component can be bent around narrow corners and is very close to the connector to minimize space occupation, save space and Simplify cable routing in narrow spaces. The flexible cable does not need to protect the back of the connector and simplifies maintenance.
