Semi-rigid Cable Assembly

Introduction

The semi-rigid cables are unique in that it is easily bent to finished shape and still maintains its set after bending. This series cables provide an advanced low-density PTFE wrapped dielectric to replace traditional solid PTFE dielectric. This series cables can effectively reduce the attenuation by 30% vs. standard semi-rigid cable. The semi-rigid cables provide greatly extended environment parameters.

FAQ

1. Hualink's 1 mm connector

The working frequency of 1 mm series can reach up to 110 GHz. They adopt reliable threaded connection methods and are applied in fields of communication, precision testing, automobiles, satellites, radar, radio astronomy and other ultra-high requirements millimeter wave fields. The dielectric adopts the air, and the thread adopts metric M4×0.7P. The design size is smaller than 1.85 mm, and it is currently the smallest millimeter wave connector in the world.

2. What's RF Coaxial Cable?

Cables can be an essential component, even a lifeline, to electronic systems. If a cable goes down, the entire system can fail.

With four critical factors impacting their performance — mechanical, electrical, environmental and application-specific — manufacturers have to make sure cables can survive severe conditions and perform reliably over the system's lifespan. Whether they’re used in systems operating on land, underground, in the ocean, air or space, cables must be built to last.

Coaxial cable is an electrical cable with inner conductor, dielectric insulator, shielding (Outer conductor) and jacket. Coaxial cable plays signal transmission role for Radio Frequency and normally will be terminated with RF connectors like SMA, 3.5mm, 2.92mm, 2.4mm, 1.85mm, 1mm, Type N, SMP, SMPM connectors to be RF coax cable assembly to connect modular and antenna.

The choice of Coax cable will affect frequency performance, flexibility, strength, attenuation, power capability and cost. Materials of inner structure decide coax cable’s performance.

Inner conductor might be solid or stranded. Solid will has lower loss, but stranded is more flexible. To get high frequency performance, the inner conductor may be silver plated. To cost down, the inner conductor may be copper clad steel. Inner conductor’s size plays an important factor to have lower loss. Bigger conductor will allow quick and smooth signal transmission, and is better choice for long length.

The insulator or dielectric wrap inner conductor, and may be solid plastic, a foam plastic or air with spacers. The common materials are PE, FEP, PTFE, and PFA.

Outer Conductor or Shielding can braided copper wire or braided alum wire or solid metal tube. To have better shield performance, some coax cables are designed to have double-layers wire braid or to have alum. Foil covered by one layer wire braid. The density of braided wire decides the shielding performance. Sometimes the braid is silver plated, tin plated or just bare copper.

Jacket can be made from many materials like PVC, FEP and PE. PE jacket can be used outdoor to have temperature resistance. PVC is more flexible and commonly is used indoor.
