Development of a high-Q multilayer ceramic resonator

It has been discovered that multilayer ceramic resonators, manufactured by a cofiring method at a temperature above the melting point of the inner conductor, have an improved Q-factor. The increase in Q-factor enabled the realization of an S-band multilayer low-loss bandpass filter (BPF). In this pa...

Zusammenfassung:It has been discovered that multilayer ceramic resonators, manufactured by a cofiring method at a temperature above the melting point of the inner conductor, have an improved Q-factor. The increase in Q-factor enabled the realization of an S-band multilayer low-loss bandpass filter (BPF). In this paper the insertion loss of the cofired BPFs is examined, and a relationship between firing temperature and Q-factor is established.
