Abstract :
A new method for implementing the wideband bandpass filter utilizing low temperature co-fired ceramic(LTCC) multilayered technology has been proposed. The circuit of this filter is composed of 9-order resonators by inductance coupling. Based on the improved structure of the tapped combline filter, combined with circuit simulation and 3D EM simulation, a wideband filter with the bandwidth from 4GHz to 11GHz is realized with the help of DOE. The fractional bandwidth is more than 93.3%. The group delay is less than 0.6ns in the bandwidth. The implemented filter exhibits a good frequency response, low insertion loss, and especially very compact size. The final size of the fabricated filter is only 3.2mm×2.5mm×1.5mm.
