Rf termination

An RF termination device for use in a system characterized by a predetermined system impedance, the device comprising:

• a substrate including a first major surface and a second major surface;
• a first meandered transmission line disposed on the first major surface, the meandered first transmission line having a predetermined first transmission line length and a characteristic impedance substantially equal to twice the predetermined system impedance, the first meandered transmission line having a first-first transmission line end portion and a second-first transmission line end portion configured as an open circuit;
• and
• a second meandered transmission line disposed on the first major surface adjacent the first meandered transmission line, the meandered second transmission line having a predetermined second transmission line length and a characteristic impedance substantially equal to twice the predetermined system impedance, the second meandered transmission line having a first-second transmission line end portion coupled to the first-first transmission line end portion and a second-second transmission line end portion coupled to a ground plane.

A method of making an RF termination device for use in a system characterized by a predetermined system impedance, the method comprising:

• providing a substrate having a first major surface and a second major surface;
• forming a first meandered transmission line on the first major surface, the meandered first transmission line having a first characteristic impedance corresponding to a predetermined first transmission line length to provide a predetermined attenuation amount, the first meandered transmission line having a first-first transmission line end portion and a second-first transmission line end portion configured as an open circuit;
• and
• forming a second meandered transmission line on the first major surface, the meandered second transmission line having a second characteristic impedance corresponding to a predetermined second transmission line length to provide the predetermined attenuation amount, the second meandered transmission line having a first-second transmission line end portion coupled to the first-first transmission line end portion and a second-second transmission line end portion coupled to a ground plane.
