Resonance method strip line type for sheet
dielectric constant and dielectric loss tangent measurement system

Catalog No.dps50002070405-07

This is a test system for dielectric constant and dielectric loss tangent where the material dielectric loss is relatively small in the vicinity of 1 to 20 in the frequency range of 800 MHz to 14GHz.
We follow the ASTMD3380-75 Standard method of Test for Permittivity (Dielectric Constant) and Dissipation Factor of Plastic-Based Microwave Circuit Substrates and IPC-L-125 Specification for Plastic Substrates, Clad or Unclad, for High Speed / High Frequency Interconnections.
