Waveguide type dielectric resonators-General information and test conditions. Measurement method of conductivity at interface between conductor layer and dielectric substrate at microwave frequency
波导型介质谐振器
BS EN 61338-1-5:2015: Microwave circuits are popularly formed on multi-layered organic or non-organic substrates. In the microwave circuits, the attenuation of planar transmission lines such as striplines,
microstrip lines, and coplanar lines are determined by their conductor loss, dielectric loss and
radiation loss. Among them, the conductor loss is a major factor in the attenuation of the
planar transmission lines. A new measurement method is standardized in this document to
evaluate the conductivity of transmission line on or in the substrates such as the organic,
ceramic and LTCC (low temperature co-fired ceramics) substrates. This standard describes a
measurement method for resistance and effective conductivity at the interface between
conductor layer and dielectric substrate, which are called interface resistance and interface
conductivity.This measurement method has the following characteristics:the interface resistanceRiis obtained by measuring the resonant frequencyf0and
unloaded quality factorQuof a TE01δmode dielectric rod resonator shown in Figure 2;the interface conductivityσiand the relative interface conductivity σri= σi/ σ0are calculated from
the measuredRivalue, where σ0= 5,8 × 107S/m is the conductivity of standard copper;the measurement uncertainty of σri(Δσri) is less than 5 %.Cross References:IEC 61338-1-3IEC 62562EN 61338-1-3EN 62252All current amendments available at time of purchase are included with the purchase of this document.
