Abstract
For low temperature co‐fired ceramic (LTCC) modules targeting radio frequency applications, a near 0 ppm/°C temperature coefficient of resonant frequency (τf) ensures temperature stability of embedded filters. The base dielectrics of most commercial LTCC systems have a τf in the range −50 to −80 ppm/°C. By integrating co‐fireable compensating dielectrics with an opposite τf to that of the host dielectric, we demonstrated multilayer stripline (SL) bandpass filters with a τf approaching 0 ppm/°C using DuPont 951 LTCC. The effective dielectric constant of the SL in multilayer LTCC with dissimilar layered dielectrics was calculated using a variational method with transmission‐line technique.
