Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
Coaxial cable assemblies are critical components in signal transmission systems, used across industries like telecommunications, aerospace, medical equipment, and industrial automation. Their bandwidth capacity—defined as the maximum frequency range over which the assembly can transmit signals with minimal attenuation, distortion, or interference—directly determines system performance. Understanding this parameter is essential for selecting the right assembly for specific applications, avoiding signal loss, and ensuring reliable data or power transfer.
Unlike standalone coaxial cables, “assemblies” include the cable itself plus connectors (e.g., BNC, SMA, N-type) and terminations. Thus, their bandwidth capacity is not just a property of the cable but a combined result of all components. A high-quality cable paired with low-performance connectors will still limit overall bandwidth, as connectors introduce impedance mismatches or signal reflection that degrade transmission at high frequencies.
In practical terms, bandwidth capacity is often specified as a frequency range (e.g., 0–6 GHz) or a maximum frequency (e.g., up to 18 GHz). For most applications, the “usable bandwidth” refers to the range where signal attenuation stays below a threshold (typically 3 dB per 100 feet for RF signals) and signal-to-noise ratio (SNR) remains sufficient for error-free transmission.
Several variables directly influence the bandwidth capacity of coaxial cable assemblies, making them critical considerations during selection:
Coaxial cables are categorized by design, with common types including:
The cable’s dielectric material also plays a role: Teflon (PTFE) dielectrics, for example, have lower signal loss at high frequencies than polyethylene, enabling wider bandwidth.
Coaxial assemblies are designed for specific impedance (e.g., 50 Ω for RF/microwave, 75 Ω for video/CATV). Mismatched impedance (e.g., a 50 Ω cable with 75 Ω connectors) causes signal reflection, which reduces usable bandwidth by creating interference at high frequencies. Assemblies with tight impedance tolerance (±1 Ω) maintain bandwidth more effectively than those with loose tolerances.
Connectors are often the “weak link” in assemblies. High-frequency connectors (e.g., SMA, 2.92 mm) are engineered to minimize signal loss:
Temperature, humidity, and vibration affect bandwidth over time. For example, extreme temperatures can degrade dielectric materials, increasing signal loss at high frequencies. Industrial-grade assemblies (rated for -40°C to 85°C) maintain stable bandwidth in harsh environments, while consumer-grade variants may see bandwidth reduction outside 0°C to 60°C.
To simplify selection, here are common coaxial cable assembly bandwidths matched to their use cases:
| Application | Assembly Type | Bandwidth Capacity | Key Use Case |
| Consumer Broadband | RG-6 + F-connectors | 0–1.5 GHz | Cable TV, residential internet |
| Industrial Control | RG-58 + BNC | 0–500 MHz | Sensor signal transmission |
| RF/Microwave Testing | Semi-rigid + SMA | 0–18 GHz | Laboratory signal analysis |
| Aerospace | Semi-rigid + 2.92mm | 0–40 GHz | Satellite communication |
| Medical Imaging | Low-loss + LEMO | 0–6 GHz | Ultrasound, MRI equipment |
Even with a high-bandwidth assembly, improper use can limit performance:
