HTK LVD-A30LMSG+ ultra-fine coaxial connection solution: a high-speed interconnect choice for thin and light devices

With the continuous evolution of smart terminal devices towards thinness, high speed, and high integration, the internal interconnect system has higher requirements for the miniaturization, reliability, and high-speed transmission capability of connectors and cables. The HTK LVD series, as a high-speed interconnect solution designed for compact devices, the LVD-A30LMSG+ with its extremely low insertion height of 2mm and excellent shielding performance has become an ideal connection solution for many high-end electronic devices.
The following will analyze from three aspects: the characteristics of ultra-fine coaxial cables, the structural advantages of connectors, and the applicable scenarios.

Part one: The superior transmission performance of extremely fine coaxial cables

Extremely thin coaxial cables are used as the core transmission materials for high-frequency signals and are widely employed in compact electronic devices such as laptops, PDAs, portable cameras, and others. Their main characteristics include:

High signal integrity

The ultra-fine coaxial cable uses a central conductor and coaxial shielding structure, maintaining a stable 50Ω characteristic impedance through high-quality insulating medium, effectively reducing reflection and distortion, ensuring stable and intact transmission of high-speed and radio frequency signals.

Excellent anti-electromagnetic interference (EMI/RFI) capability

The metal braided or metal foil shielding layer forms a continuous shielding, which can block external interference and suppress signal leakage, improving the reliability and anti-interference performance of signal transmission.

Wide Frequency Response and High Bandwidth

A reasonable cable structure design can support applications at hundreds of MHz and even higher frequencies, meeting the needs of high-definition video transmission, high-speed digital interfaces, and wireless communication systems.

4. Low-loss characteristics

Utilizing high-performance insulating materials and precise structures, it significantly reduces transmission loss and is particularly suitable for high-speed signal transmission over short distances, improving the overall link quality.

Excellent flexibility and durability

The cable has an extremely thin wire diameter and strong flexibility, allowing for free wiring in compact spaces. It also has strong bending and tensile resistance, suitable for dynamic environment scenarios.

6, Wide temperature range adaptation

Extremely thin coaxial cables can operate stably within a temperature range of -55°C to +85°C, adapting to various equipment environments.
