PTFE (Teflon ®) INSULATED RF COAXIAL CABLES
 

Coaxial cable consists of a core conductor, surrounded by PTFE dielectric, covered with a metal shield and finally encased in a insulating jacket. The shield provides the return path as well as the confinement for RF energy, and is generally grounded.

Coaxial cable is a transmission line – it allows transmission of high frequency energy and signals with low loss with reflection-less matching and with minimal Phase and Amplitude distortion.

GARG offers customized coaxial cable designs ranging from 1.0 mm OD subminiature and standard miniature to high power sizes. These designs provide greater packaging density, signal fidelity, low noise, flex durability, lower capacitance and propagation delay. There is also a choice of flexible or semi-rigid constructions.

What is a Triaxial Cable

 
 
 

GARG Advantages

  • PTFE Jackets over Coaxial Cables are difficult -- But They are our specialty
  • Characteristic Impedance tested on 100% length by on a Time Domain Reflectometer
  • Attenuation (signal loss) measured on samples
  • Attenuation of cables processed by us is 10 to 25% lower than the permissible maximum given in US MIL-C-17.
  • Low micro-phonic noise cables (less than 5 micro-volts) for sensitive transducer interconnects and very low capacitance cables for instrumentation (e.g. 1.8 mm OD with 40 pF/m).
  • Miniature & Subminiature RF Coaxial And Triaxial Cables
  • Designed to customer specifications
  • Over forty years experience in PTFE coaxial cables field
  • Supplier for many critical applications requiring high reliability

How To Select

Advantages of PTFE as insulation Material

  • PTFE is one of the lowest dielectric constant and loss factor material
  • Inert to practically all chemicals even at elevated temperatures
  • Fire (flame) proof
  • Smaller size, lighter weight and much higher reliability
  • Excellent thermal stability for use from -60C to 260C
