Abstract

A combiner/divider may comprise a circuit ground and five transmission lines. The first transmission line may include a first conductor having a first end forming a first unbalanced-signal port relative to the circuit ground, and a second conductor having a first end connected to the circuit ground. The second and third transmission lines may be connected in parallel and each may include a conductor connecting a second end of the first conductor to a first balanced-signal port. The fourth and fifth transmission lines may be connected in parallel and each may include a conductor connecting a second end of the second conductor to a second balanced-signal port. A ferrite sleeve may surround the second and third transmission lines and/or the fourth and fifth transmission lines. The second, third, fourth and fifth transmission lines may be coaxial transmission lines with connected outer conductors.
