A W-Band Dual-Mode Band-Pass Filter Based on LTCC Technology

Abstract:

In this paper, a W-band dual-mode substrate integrated cavity fourth-order band-pass filter is presented, which utilizes LTCC technology. The filter is composed of two dual-mode resonators which are constructed by rows of via arrays in the substrate layer. Two coupling vias near particular diagonal corners are set to perturb the two degenerate modes in each cavity and thus to generate an intra-cavity coupling. The filter exhibits 3dB bandwidth about 2.4GHz, return loss better than 19dB and out of band rejection better than 30dB. The filter occupies the area of 3.752mm4.064mm (including the two feeding lines) in the LTCC substrate.
