Abstract :
One new type of laminated ceramic interdigital bandpass filter manufactured by low temperature co-fired ceramic (LTCC) technology is presented in this article. The designed filter is constructed of conductive patterns, which are printed on various ceramic sheets. The patterns include three stepped-impedance resonators arranged in interdigital manner, and series resonance branches for transmission zeros. The simulated result for this component shows broad bandpass width plus enhanced bandstop rejection.
