Abstract :
Various band-pass filter configurations with improved stop-band characteristics are analyzed and implemented based upon the Low Temperature Co-Fired Ceramic (LTCC) technology. Design equations that take into account the effect of the transmission zeros are formulated. For illustration, a 2.4 GHz RF filter with transmission zeros located at 2.2 GHz is fabricated and characterized. Both EM simulation and experimental results are presented
