KEYCOM provides solutions in the 300 GHz to 1 μHz frequency range (SHF/EHF/MW/UHF/VHF/ULF).
We undertake designing, manufacturing and measuring. Please feel free to contact us.

Magnetic Property Characteristics (including magnetic permeability)
Measurement System (widely measurable in the range of 100kHz to 30GHz)

Model No. PER01
Wide measurement range from 100 kHz to 30 GHz, Eliminating the effect of dielectric constant to correspond well with simulation results!

1. Seamless and Wide Coverage of Bandwidth

The system seamlessly covers a wide bandwidth from 100 kHz to 30 GHz.

2. Measurable Value

The system can provide a wide range of frequency for measuring complex permeability μr' - jμr" (20~30 GHz is available in our measurement service), half-width ΔH, and ferromagnetic resonance relaxation coefficient α (100 MHz~10 GHz) of magnetic materials.

3. Compact device, Simple measurement

With our system, you can achieve a highly accurate measurement simply by making frequency sweep using a vector network analyzer, after setting a sample on the jig.

1) Clear measurement principle --- Reflection method
2) Simple operation method --- Field method, Remove method
3) Compact device --- free transport

If you need to measure only a small amount of sample or you have some specific requirement in measurement condition(e.g. frequency), please feel free to contact KEYCOM's measurement service center.

The measurement method has been standardized in IEC 60556-2006
