Abstract

A tapped-line stepped-impedance resonator band-pass filter was implemented using a low temperature cofired multilayer-ceramic structure. By constructing a multilayer structure, a compact band-pass filter was realized. Moreover, the multilayer structure demonstrated an extra cross-coupling effect that produced extra transmission zeros in the stopband and, hence, realized a highly steep passband skirt. The center frequency of the fabricated band-pass filter was 6.075 GHz and the 3 dB fractional bandwidth was 18%. The measured insertion loss and return loss of the filter were -0.31 dB and -28 dB, respectively. The measured response of the fabricated band-pass filter was in good agreement with simulated results.
