A fifth transmission line may be connected in series with the fourth transmission line and have a fourth balanced-signal port. In some examples, the transmission lines may be coaxial. Balanced signals may exist between the first and second balanced-signal ports and between the third and fourth balanced-signal ports. Series-connected coaxial transmission lines may be formed of a single coaxial line with a gap in the outer conductor separating the two coaxial transmission lines.

摘要： A radio-frequency impedance device includes a resistor device mounted on a surface of a dielectric layer, and adapted to be connected between a transmission line and an output terminal associated with a load impedance. A ground conductor may extend opposite a portion of the resistor device. Further, a conductor assembly may couple a first end of the resistor device to a transmission line. The conductor assembly may include a first portion extending along the first layer face on opposite sides of the resistor device adjacent to at least the first resistor end, or a second portion extending along the fourth layer face opposite from the ground conductor. The configuration of devices may produce, in operation, an electric field distributed along the resistor device, providing corresponding distributed current density along the resistor device over a broad frequency band.
