GB/T 9633-2012Measuring methods for properties of gyromagnetic materials intended for application at microwave frequencies (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 9633-1988 "Test Method gyromagnetic material properties of microwave frequency applications." this standard compared with GB/T 9633-1988, the main changes are as follows.

--- Original standard was more than 10 editorial changes and unify the terminology, such as precision, accuracy unified accuracy.

--- Block diagram, schematic block diagram of a unified, instruments and devices, means unified device.

--- Magnetic constant µ0 to magnetic constant µ0.

--- "Core" unified "core"; with the multiplication sign "×" instead of the dot "..."

--- Reg number with the original standard to do a larger adjustment.

--- Original standards - Part 2 4.5 penultimate paragraph "Amplifier sensitivity should be more than 2m/V" to "spiritual amplifiers Sensitivity should be more than 2mm/mV "; the original standard Figure 21" 9.1MHz "to" 9.1GHz "; the original 9.6 standard measurement procedures last A "measurement should be completed by 25 °C and relative humidity of about 65% of the environment" to "measurement should be done at room temperature."

--- Formula "log" be replaced by "lg".

--- Remove the spin magnetic resonance linewidth (general and GHz) measurement procedure in Method a) (see the 1988 edition of Chapter 5 ~ Chapter 6).

--- Remove the original standard formula (33b) (see 1988 edition 6.3).

This standard is identical with IEC 60556:2006 "gyromagnetic material properties measurements of microwave frequency applications." the editorial changes made the following standard.

--- "This International Standard" by "this standard."

--- References in some standard by adopting international standards to replace national standards or industry standards, and increases appearing in FIG. 18 IEC 60153-2. 1974.

--- Remove the IEC standard preface.

--- To define terms and definitions.

--- The IEC standard reference chapters unified prepared and added at the end of the domestic references.

Correspondence between the consistency of the standards of international documents and normative references of the following documents.

The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

This standard by the national magnetic components and ferrite materials Standardization Technical Committee (SAC/TC89) centralized.

1 Scope

This standard specifies the measurement method is in accordance with SJ/T 11077-1996 "microwave ferrite specification drafting guidelines" multi-crystal micro stipulated Performance and methodology are generally used in the process of ferrite waves.

This standard applies to the measurement methods used for research applications at microwave frequencies ferrite material.

This standard does not exclude other measurement methods commonly used, but it should be controversial to this standard measuring method for arbitration.

This standard does not include a single crystal and thin film materials.

Note 1. This standard concept of "ferrite" and "microwave" is broad. "ferrite" means not only having a spinel crystal structure of the magnetic - dielectric chemical component, but also refers to a material having a garnet and hexagonal crystal structure.

"Microwave" includes a wavelength range of about 1m ~ 1mm between, and the scope is primarily concerned with 0.3m ~ 10mm.

Note 2. Microwave ferrite material is mainly used for non-reciprocal devices, such as circulators, isolators, non-reciprocal phase shifter. However, these materials may be used reciprocal devices, e.g.

Modulators, and (reciprocal) phase shifter. Other applications include rotating magnetic filter, limiter and more complex devices, such as parametric amplifier.
