Abstract :
This paper presents the design and optimization for the transition performance between 4-mil LTCC line and 8-mil LTCC line. The high frequency performance can be improved by adding vias connecting the ground of the 4-mil microstrip and ground of 8-mil microstrip. We further adjust number of vias and their relative positions to achieve a return loss better than 20dB from DC to 65GHz.
