INFO

The rapid evolution of 5G technology has brought about a paradigm shift in wireless communication, with Multiple-Input Multiple-Output (MIMO) technology standing as a cornerstone for achieving the high data rates, low latency, and massive connectivity that 5G promises. As MIMO systems scale up to support more antenna elements—from 4×4 to 8×8, 16×16, and beyond—the demand for high-performance, compact, and reliable signal transmission components has never been greater. Among these components, micro-coaxial cables have emerged as a critical enabler, addressing the unique challenges posed by 5G MIMO architectures.

5G MIMO systems operate at higher frequency bands, including sub-6 GHz and mmWave (24 GHz and above), to unlock greater bandwidth. However, higher frequencies are inherently more susceptible to signal loss, interference, and impedance mismatch. Traditional coaxial cables, while effective for lower-frequency applications, often fall short in 5G MIMO scenarios due to their larger size, higher insertion loss, and limited flexibility—issues that become exacerbated when routing cables between densely packed antenna arrays and radio units (RUs).

Micro-coaxial cables, by contrast, are engineered to overcome these limitations. With an outer diameter typically ranging from 0.8 mm to 2.0 mm, they offer exceptional space efficiency, making them ideal for use in compact 5G MIMO devices such as small cells, massive MIMO base stations, and even consumer electronics like smartphones and tablets with embedded MIMO antennas. Their small form factor allows for easier routing in tight spaces, reducing the risk of signal crosstalk between adjacent cables—a common problem in densely wired MIMO systems.

Beyond size, micro-coaxial cables deliver superior electrical performance tailored to 5G MIMO requirements. Key include:

  • Low Insertion Loss: Constructed with high-purity copper conductors and low-dielectric-constant insulators (such as PTFE or FEP), micro-coaxial cables minimize signal attenuation even at mmWave frequencies. This ensures that the weak high-frequency signals transmitted between MIMO antennas and RUs remain strong and intact, preserving data integrity and reducing the need for additional signal amplification.
  • Controlled Impedance: 5G MIMO systems require precise impedance matching (typically 50 ohms) to maximize power transfer and minimize signal reflection. Micro-coaxial cables are manufactured with tight tolerance controls, ensuring consistent impedance across their length and reducing standing wave ratio (SWR)—a critical factor in maintaining system efficiency.
  • Excellent Shielding: To combat electromagnetic interference (EMI) and radio frequency interference (RFI) in crowded 5G environments, micro-coaxial cables feature robust shielding, such as braided copper or aluminum foil. This shielding prevents external interference from disrupting MIMO signals and also contains internal signals, reducing crosstalk between cables in multi-cable assemblies.
  • Mechanical Durability: 5G MIMO infrastructure, especially outdoor base stations and small cells, must withstand harsh environmental conditions, including temperature fluctuations, moisture, and vibration. High-quality micro-coaxial cables are jacketed with durable materials like PVC, PE, or TPU, providing resistance to abrasion, chemicals, and UV radiation, ensuring long-term reliability in demanding deployments.

The practical applications of micro-coaxial cables in 5G MIMO are diverse and far-reaching. In massive MIMO base stations, which can feature hundreds of antenna elements, micro-coaxial cables serve as the “nervous system” connecting each antenna to the RU, enabling the precise beamforming that is essential for directing signals to specific users and mitigating interference. In small cells—deployed in urban canyons, stadiums, and indoor spaces—their compact size and flexibility allow for easy integration into existing infrastructure without disrupting aesthetics or functionality.

Even in consumer devices, micro-coaxial cables play a vital role. Modern smartphones with 5G MIMO capabilities rely on micro-coaxial cables to connect internal antennas to the device’s modem, ensuring seamless signal transmission while fitting within the device’s slim form factor. As consumer demand for faster 5G speeds grows, the quality of these micro-coaxial cables directly impacts the end-user experience.
