From 100kHz to 20GHz Magnetic Property Characteristic(permeability µr' and others)Measurement System

Measurement of magnetic property characteristics by using vector network analyzer.
Without shaping specimens into toroidal form, accurate measurement is available.

When you design or study high performance microwave magnetic devices, it is very important to know magnetic property characteristics of their materials. For this purpose, simple and easy operation way to measure magnetic properties is essential. The most important parameters of high frequency magnetic materials to be measured are as follows :

  • Complex permeability
  • Ferromagnetic resonance (FMR)
  • Relaxation coefficient α
  • g-factor
  • FMR linewidth ΔH

This compact and easy-to-use measurement system offered by Keycom can measure all these parameters.
To measure with this system, it is necessary to connect a shielded and shorted microstrip line jig to a vector network analyzer.
Keysight technologies’ PNA and ENA series are available for this measurement.

Standardization
IEC 60556 Ad2・2(2016)
