Abstract

The competence of integrating circuits within LTCC materials is an added advantage to implement the material in electronic circuits. Since the circuits are buried inside the material, it is not easy to tune the circuit if the required performances are not achieved. Therefore precise knowledge of microwave properties of Low Temperature Co-fired Ceramic (LTCC) materials is crucial before designing the circuit for the efficient design of microwave systems, especially for design of communication filters. Many communication devices operate at low temperatures. In order to implement LTCC at low temperature communication circuits and devices, engineers need precise values of the complex permittivity. The aim of this paper is to characterize LTCC material as a function of temperature at microwave frequencies using a very precise measurement technique, Split Post Dielectric Resonator. DuPont Green Tapes were characterized in the temperature range of 20 K – 300K at a frequency of 9.5 GHz.
