This standard describes a method for determining the relative permittivity and loss tangent of copper clad laminates at microwave frequencies (from 1,1 GHz to 20 GHz) using a split post dielectric resonator (SPDR). This method applies to the measurement of copper clad laminates and dielectric base materials. Figure 2 shows the component diagram of the test system. The frequency range of the vector network analyzer shall be 500 MHz to 20 GHz. The dynamic range of the vector network analyzer shall be more than 60 dB. Figure A.1 shows an SPDR test apparatus with a nominal frequency of 5 GHz. A 3.5 mm female-to-female adapter shall be used to connect the coaxial cable to the SPDR test apparatus. To set the coupling coefficient, the SPDR test apparatus is provided with a coupling loop at each end. The maximum thickness of the specimen for this test apparatus is 2 mm. The responsible committee is DKE/K 682 "Montageverfahren für elektronische Baugruppen" ("Electronics assembly technology") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
