摘要：
This paper develops a new multilayered wide-passband bandpass filter with the assistance of low-temperature co-fired ceramic technology. The mutually inductive coupling between the input and output port of a low- and high-pass filter cascaded in the proposed filter is utilized as well. The results show that in the passband of 3.1-4.9 GHz, the measured insertion loss and return loss of this filter are less than 1.1 dB and greater than 18 dB, respectively. In addition, the insertion loss from dc to 2.76 GHz is greater than 20 dB, and the one from 5.8 to 12 GHz is greater than 30 dB.
