As electronic devices develop towards thinness and high speed, the application of extremely fine coaxial cables (micro coaxial cable) in precision connection fields is becoming more and more extensive. Especially in high-frequency signal transmission scenarios, the signal testing of extremely fine coaxial cable bundles is particularly important. This article will focus on the key indicators of signal testing for extremely fine coaxial cable bundles, and introduce the features of the high-performance connector I-PEX 20680-060T-01.
Key Indicators for the Test of Ultra-Fine Coaxial Beam Signal
Extremely thin coaxial cables, with their ultra-small diameters and excellent shielding properties, are widely used in high-definition cameras, mobile devices, medical instruments, and other high-end electronic products. When conducting signal tests, the following indicators should be paid attention to:
Insertion Loss: It indicates the energy attenuation of the signal as it passes through the cable, with a lower value indicating higher signal quality.
• Return Loss: Reflects the degree to which the signal is reflected back to the source. The higher the return loss, the more stable the signal transmission.
• Crosstalk: The interference between adjacent wires in a multi-wire environment, where low crosstalk indicates purer signals.
Impedance matching: Connectors with consistent impedance with cables can reduce signal reflection and transmission loss, ensuring signal integrity.
• Environmental Resistance: Includes the influence of environmental factors such as temperature, humidity, and mechanical vibration on signal performance, and high-quality wire harnesses should have good tolerance.
• Transmission Delay (Propagation Delay): The time required for a signal to travel from the input end to the output end. The smaller the delay, the more suitable it is for high-speed data transmission needs.
