Baiyin SR Series Semi-rigid Cables: Low-Loss, High-Reliability Coaxial Cable Choice for RF/Microwave Engineering

Baiyin SR Series Semi-rigid Cables: Low-Loss, High-Reliability Coaxial Cable Choice for RF/Microwave Engineering

In the field of RF and microwave engineering, semi-rigid cables are one of the core media for ensuring stable transmission of high-frequency signals. Baiyin's SR series semi-rigid cables, with their specialized product features and excellent performance, have become the preferred transmission solution for engineering in this field. Baiyin SR series semi-rigid cables, replaces Micro-Coax's UT series, and is equivalent to domestic model SFT series.

I. What is a Semi-rigid Cable? A Dedicated Coaxial Cable for RF and Microwave Applications

Semi-rigid cables are a type of coaxial cable that falls between rigid and flexible cables, combining "shape retention" and "manufacturability." They enable low-loss signal transmission in the RF and microwave frequency bands, making them a key transmission medium for high-frequency applications such as communication and testing. Baiyin's SR/SFT series semi-rigid cables are dedicated products in this category, designed specifically for the precise transmission needs of RF/microwave engineering, and are currently one of the mainstream choices in this field.

II. Core Functions of Baiyin SR/SFT Series Semi-rigid Cables

1. Multi-Impedance Signal Transmission

Covering 50Ω (mainstream RF/microwave standard) and subdivided impedance specifications such as 10/15/25/75/100Ω, adapting to the transmission matching needs of different high-frequency signals.

2. Flexible Adaptability to Engineering Layouts

Outer diameter sizes range from 0.50mm to 9.9mm, with single continuous lengths up to 30 meters, meeting the cabling length and space adaptation requirements of different engineering scenarios.

3. Stable High-Frequency Signal Transmission

As a coaxial cable, it ensures low distortion during RF/microwave signal transmission, supporting precise signal interaction in equipment.

III. Core Advantages of Baiyin Series Semi-rigid Cables

1. Lower Transmission Loss

The 50Ω specification Baiyin semi-rigid cable reduces signal attenuation by 20%, significantly improving signal transmission efficiency in RF/microwave scenarios.

2. Ultra-wide Temperature Range Tolerance: Operating temperature up to 250℃, and passed the "DS" high-precision test (150℃/1 hour high-temperature environment), avoiding the copper tube bursting and bulging problems of traditional semi-rigid wires.

3. Diverse Materials and Processes: The outer conductor supports copper, aluminum, stainless steel, and other materials, with strict requirements for the silver plating process, balancing transmission performance and environmental durability.

4. Customizable Adaptability: Meets the special requirements of "non-magnetic" scenarios, and can also be customized according to project needs, allowing for adjustments to parameters such as inner conductor strength and bending radius.

IV. Typical Application Scenarios of Baiyin SR Series Semi-rigid Cables

Due to their low loss and high tolerance characteristics, this series of semi-rigid cables is mainly suitable for RF/microwave related projects:

(1) Aerospace avionics systems  

(2) Precision test and measurement instruments

(3) Medical high-frequency equipment

(4) Industrial high-frequency testing equipment

With its detailed specifications and customization capabilities, Baiyin SR/SFT series semi-rigid cables have become a highly reliable choice for RF/microwave engineering.
