67 GHz RF Cables

Introduction

Our assemblies offer excellent electrical performance in applications from DC through 67GHz. It offers low loss, light weight, and high phase stability versus mechanical and temperature changes. This cable series features a silver-plated copper center conductor, low density PTFE dielectric, silver-plated copper ribbon inter braid and a silver-plated copper braid shield, and blue FEP outer jacket. 1.85 mm right angel cables are also available and price is very competitive. Welcome to inquire!

FAQ

1. What is Cable?

Cable is a transmission line through which electromagnetic energy is propagated and transferred from one place to another

■ Usually very few impedance changes or discontinuities in a long length

■ Usually very few reflections, but Attenuation is important.

2. Care and Handing Instruction of cable assembly

A recent study showed that globally more than 75% of microwave/RF cable assemblies are replaced frequently due to damage during installation or operation. Hualink cable assemblies of all types offer a long service life providing they are treated with the appropriate care and attention. Microwave cable assemblies are high precision system components and require proper handling in order to ensure that measured performance values are maintained. To achieve the maximum installed performance the following guidelines should be followed

■ Mating life assumes the use of a calibrated torque wrench, interfaces are clean and within mil specs limits.

■ Ensure that the surroundings are clean and free of dust, dirt and any other particles that could enter unsealed connector interfaces

■ Use protective caps to prevent contamination whenever connectors are unmated

■ Where interfaces are contaminated, particles can be removed with dry, oil-free compressed air. Please use eye-protection, Interfaces can be cleaned with dry cotton swabs. Do not us hard hand tools or solvents. Do not blow into interfaces or use normal compressed-air

■ Choose the installation routing using the largest bend radii possible Small bend radii may affect electrical performance. Exceeding the specified limits during the installation process could cause a permanent degradation

■ Assemblies should be fixed in place without excess pressure. The use of cable ties should be avoided where possible, as they can easily exert more force than this. If cable ties must be used then they should be as wide as possible and still allow movement of the cable. Avoid placing fixings at regular intervals

■ Examine interfaces for damage and/or contamination before mating

■ Discharge connectors before mating or ensure that they are connected to a suitable ground

■ When mating connectors with a screwed interface always hold the connector bodies and turn only the coupling nut. This avoids twisting the cable and ensures minimum wear on the connector pins

■ Do not exceed the specified torque
