Abstract

In this paper, a vertical via transition using a coaxial line is presented for LTCC SMT package applications. A part of outer conductor is cut off due to overlap between a CPW on PCB and transition. For reduction of radiation and return path, a cap is designed on the top layer. The measured S11 and S21 are -14 and 0.9dB, respectively at 15GHz.
