A new low-temperature co-fired ceramic (LTCC) bandpass filter using three-dimensionally coupled helical inductors is presented. The resonator is a via-connected multilayer helical inductor and the filter uses mixed coupling between face-to-face inductors. The fabricated filter exhibits the center frequency of 5.8 GHz, 3-dB bandwidth of 800 MHz, and the insertion loss of 1.9 dB. The size of the active region is 1.7 x 2.3 x 0. 8 min(3). The measured results are consistent with the three-dimensional electromagnetic simulation and the equivalent circuit modeling. (c) 2007 Wiley Periodicals, Inc.
