Millimeter wave, Microwave Transmission Line ( Coaxial Cable etc )

Model No. mmt

KEYCOM focuses on development and flexibilization of products for low-loss, sub-millimeter wave field by optimizing the knowledge of dielectric materials accumulated over a long period of time. (Products: cables, dielectric waveguide, microstrip line, microstrip track, etc.)


Millimeter wave / Microwave Flexible Coaxial Cable Assembly

This flexible coaxial cable can be easily and freely bent by hands to fit to or in your devices.
Based on its longtime experience in the industry, KEYCOM’s cable assemblies are designed to be simple yet practical.
Because PTFE foam is used for the dielectric insulation, this cable assembly possesses low loss and high phase stability.
It is also ideal for measurement applications.

Millimeter wave / Microwave Easily Formable Coaxial Cable Assembly
Its easily formable coaxial cable body can be flexibly
bent to fit to your devices, and maintains its shape.
It is durable enough for tens of times of repeated bending.
Millimeter wave semi-rigid coaxial cable assembly
This semi-rigid coaxial cable is easy to install to or in your devices if it has been preliminarily bend-processed.
It possesses very small insertion loss and outstanding return loss characteristics.
Dielectric Waveguide Assembly for Millimeter Wave
With its transmission part being made only of dielectrics, this dielectric waveguide assembly possesses flexibility and extremely low insertion loss for millimeter waves.
It is suitable for insulation of high voltage, or between cryogenic temperature and room temperature.
