Bi2(Li0.5Ta1.5)O7 ceramics possess a εr of 65.1, a Qf of 15 500 GHz and a TCF of −17.5 ppm °C−1. The sintering temperature was lowered to 920 °C by the addition of 2 mol% Bi2O3, which makes them potential candidates for dielectric resonators and LTCC applications.

Measurement Results

The applicability of the various copper compositions to the production of thick-film microwave devices has been examined. The results of this work are presented in this paper. The paper presents criteria and computer programs for thick-film microwave integrated circuits. The investigations of asymmetrical striplines, stripline and circular resonators, microwave filters etc., have been used as a basis. The circuits were examined within the frequency band of 1–12 GHz. Based on the measurement results and the statistical analysis of the parameters of microwave integrated circuits, interesting conclusions concerned with the applications of thick-film techniques to microwaves have been drawn. The results obtained have been compared with other work and new mathematical models have been prepared. Finally the future development of microwave integrated circuits has been commented on.

High Dielectric

Over the past ten years several new ceramic materials have been developed for incorporation in high quality microwave integrated filters. A suitable ceramic dielectric microwave resonator material must have low loss in the microwave region, a low temperature coefficient of dielectric constant, and a high dielectric constant, typically 35-40. Most of the research conducted on the ceramic systems has focused upon phases in the BaO-TiO2 system. Many of the barium polytitanates have dielectric properties suited toward their use in microwave filters. Ba2Ti9O2O and BaTi4O9 are used commercially in the communications industry, and BaTi5O11 may also be a potential candidate for use in these systems.
