Magnetic Property Characteristics
Measurement System (from 100kHz to 30GH)

Model No. PER01
This measurement system covers wide frequency range from 100kHz to 30GHz ! It excludes influence from permittivity, so you can get measurement data corresponding to your simulation !!

KEYCOM’s magnetic property characteristics measurement system delivers ideal measurement solutions for complex permeability μr'- jμr'', ferromagnetic resonance relaxation coefficient α, resonant line width ΔH in wideband from 100kHz up to 30GHz(* As for requests about the range from 10 - 30GHz, please use our measurement service.).
Its simple measurement process of setting your disk or square specimen on the microstripline and sweeping the frequency with your vector network analyzer makes your measurement easier and more accurate.

1. Clear measurment principle - Reflection method
2. Simple operation method - Field method, Remove method
3. Compact device - Easy to carry
