Abstract:
1. A radio frequency (RF) communication device, comprising: an RF signal combiner comprising: wherein the conductive trace of the second section is formed on a layer different from a layer on which the conductive trace of the first section is formed and different from a layer on which the conductive trace of the third section is formed, wherein the conductive trace of the fifth section is formed on a layer different from a layer on which the conductive trace of the fourth section is formed and different from a layer on which the conductive trace of the sixth section is formed wherein the layer on which the conductive trace of the second section is formed is different from the layer on which the conductive trace of the fifth section is formed, wherein the conductive trace of the second section is located in proximity to the conductive trace of the fifth section to allow signal coupling between the conductive trace of the second section and the conductive trace of the fifth section, and wherein the conductive trace of the second section is not in direct contact with the conductive trace of the fifth section.
