Abstract:
1. A transmission line for high-frequency differential signals and having a transforming impedance, said transmission line comprising: a dielectric body; a first transmission line section that is comprised of a first slot in said dielectric body and having first and second transmission line ends and a first characteristic impedance between said first and second transmission line ends; a second transmission line section that is comprised of a second slot in said dielectric body, said second transmission line also having first and second ends but having a second characteristic impedance between its first and second ends; and, an impedance transition section of transmission line, having a first end coupled to the second end of said first transmission line section and a second end coupled to the first end of said second transmission line section, the first end of said impedance transition section having said first characteristic impedance, the second end of the impedance transition section having said second characteristic impedance.
