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

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'' in wideband from 100kHz upto 30GHz(* As for requests about the range from 20 - 30GHz, please use our measurement service.). Also provides ferromagnetic resonance linewidth ΔH and relaxation coefficient α from 100MHz upto 10GHz.
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
