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.

New and novel organic-based composite materials for the use of embedded RF capacitors have been developed to address the important material issues by means of functional filler and resin chemistry. Combining different fillers with appropriate chemistries, the net composite can be made thermally stable while retaining the high dielectric constant and low loss. These composites attained dielectric constant of above 7 without compromising the quality factor in GHz frequency range. In addition, measurement of capacitance variation as a function of temperature (TCC) showed flatter TCC profile, resulting in TCC of ±30 ppm/°C over the temperature range −55°C to 125°C. It can be incorporated into organic chip package and, unlike ceramic-based LTCC they can utilize large area processing that is typical, and available in high volume manufacturing. This material is formulated for RF module designers to successfully implement embedded RF capacitors into their organic chip package designs and thus improve form factor, electrical performance and possibly reduce overall costs.
