Semi-Rigid Cable Assemblies

Semi-rigid cable assemblies are high-performance products widely used in the radio frequency (RF) and microwave fields, capable of meeting a variety of complex connection and signal transmission requirements. The semi-rigid structure allows the cable to maintain a fixed shape. Once installed, it is less likely to shift or deform, ensuring the reliability of connections and the stability of signal transmission. Therefore, it is suitable for complex wiring systems with high stability requirements.

The product comes in a wide range of models. Take the FR710S & FR710/GUT - 085 086" series as an example. Different models are suitable for different frequency ranges and device interfaces. For instance, the FR710S - SMMSMM - XXX model is equipped with SMA male connectors, has a frequency range from DC to 26.5GHz, and a return loss/voltage standing wave ratio of 1.30.

The center contact is made of gold-plated brass or gold-plated beryllium copper. For the outer contact, you can choose from gold-plated brass, gold-plated beryllium copper, passivated stainless steel, etc. The main body material is similar, which has good electrical conductivity and corrosion resistance. The insulating medium is selected from PEI or PTFE. The central conductor of the cable is silver-plated copper-clad steel, and the insulating layer is solid PTFE. The sheath can be made of no material or FEP, which ensures the signal transmission performance

Due to their excellent performance, semi-rigid cable assemblies play a crucial role in numerous fields with stringent requirements for signal transmission. They are widely used in various industries such as communications, electronics, and aerospace.

Electronic warfare equipment needs to operate in high-intensity electromagnetic interference environments. The high shielding effectiveness and stable electrical performance of semi-rigid cable assemblies make them an ideal choice for internal connections in electronic warfare equipment.

In the complex systems of spacecraft, semi-rigid cable assemblies are used to connect various instruments and devices.
