A new low-loss high-k temperature-compensated dielectric for microwave applications

Abstract

A new dielectric material has been developed with a temperature-stable dielectric constant of 38. The low loss exhibited at microwave frequencies, the excellent reproducibility, and the good mechanical properties of this dielectric make it an attractive substrate for microstrip circuits. The dielectric is also suitable for the resonant elements of dielectric filters and stabilizing cavities for hybrid solid-state sources.
