75 Ohm Qr Series Aluminum Tube Cable Suppliers

Impedance stability performance characteristics of 75 Ohm Qr Series Aluminum Tube Cable from Hangzhou Putianle Cable Co., Ltd.

The 75 Ohm QR Series Aluminum Tube Cable from Hangzhou Putianle Cable Co., Ltd. is designed specifically for high-frequency signal transmission. Known for its exceptional electrical characteristics and stability, this coaxial cable is widely used in broadcasting, television, satellite communication, and data transmission. One of its standout features is its impedance stability, which is critical for maintaining signal integrity and minimizing losses during transmission.

Impedance is a measure of how much a circuit resists the flow of electric current. For coaxial cables, maintaining a consistent impedance is crucial because it ensures efficient signal transfer. A standard impedance of 75 Ohms is ideal for video and RF applications. If the impedance is mismatched, it can lead to several issues:

Mismatched impedance causes part of the signal to be reflected back towards the source, resulting in interference and signal degradation.
Loss of Signal Integrity: High levels of reflection can distort the original signal, leading to a loss of quality, especially in high-definition applications.Variations in impedance can contribute to increased insertion loss, where the signal strength diminishes as it travels through the cable.

The QR Series Aluminum Tube Cable incorporates several design features that enhance its impedance stability:

The coaxial design inherently supports a uniform impedance along the length of the cable. This structure minimizes variations in the electromagnetic field, ensuring consistent performance.

The use of aluminum for the outer conductor not only reduces weight but also allows for precise control over the cable's physical dimensions. This precision helps maintain consistent impedance across varying lengths of cable.

The dielectric material used in the QR Series cable is designed to have low loss characteristics and stable dielectric constant, which is essential for maintaining impedance stability. This insulation minimizes signal degradation and reflection.

The center conductor's design is optimized to ensure a consistent electrical path. Whether using copper-clad aluminum or pure copper, the conductor’s geometry is engineered to provide uniform resistance and minimize signal loss.

To ensure impedance stability, the QR Series cables undergo rigorous testing during manufacturing:

Each batch of cable is tested for its impedance consistency using advanced testing equipment. This ensures that the impedance remains within ±1 Ohm of the specified 75 Ohm rating.

Return loss, which quantifies the amount of reflected signal, is measured to ensure minimal signal reflection. A higher return loss value indicates better impedance matching.

TDR is employed to analyze the cable’s response over distance, identifying any irregularities in impedance that could lead to performance issues.

The cable’s performance is also evaluated under varying environmental conditions. Consistency in impedance under these conditions is crucial for outdoor and industrial applications.

The stable impedance characteristics of the 75 Ohm QR Series Aluminum Tube Cable make it suitable for a range of applications:

In these applications, high-quality signal transmission is critical. The impedance stability ensures that video signals remain clear and undistorted, crucial for HD broadcasts.

The cable's performance in high-frequency ranges makes it ideal for satellite applications where signal integrity is paramount for effective communication.

The QR Series cable is also suitable for high-speed data transmission, where stable impedance helps reduce latency and maintain high data rates.

In video surveillance systems, the cable’s ability to deliver high-quality video signals without degradation ensures that monitoring systems function effectively.
