Abstract: The frequency-dependent maximum average power-handling capabilities (APHCs) of single and edge-coupled microstrip lines (MLs) on low-temperature co-fired ceramic (LTCC) substrates are investigated in this article. Although LTCCs have excellent high-frequency performance, the thermal conductivity is about 2.0-3.0 W/m°C, which is much smaller than that of sapphires, alumina, silicon, and GaAs. The method used to predict the APHC is based on the calculated conductive and dielectric attenuation constants for different modes, and the proposed multilayer thermal model for the temperature rise. Numerical investigations are carried out to examine the effects of geometric and physical parameters on the wideband pulse responses and maximum APHC for single finite-ground thin-film and coupled MLs, respectively. Methodologies to enhance the power-handling capability which are useful in the design of high-density microstrip interconnects on or embedded in multi-layer LTCCs are proposed. © 2005 Wiley Periodicals, Inc.
