Resonator method: Split cylinder resonator for permittivity measurement 10 GHz-80 GHz
Order at 
Easy to use mm wave low loss dielectric test
- Ideal for evaluating low loss dielectric materials with tan δ 0.01 or less
- Easy and reproducible dielectric material measurement in millimeter wave band with excellent fixture design
- Unique excitation mechanism extends the upper limit frequency to 80 GHz
The millimeter wave material market has changed drastically by 5G and automotive radar, which requires an easy to use and accurate material test solution at mm wave frequencies. Answering this requirement, our split cylinders are very widely used in the growing markets.
