Patent ID: 8648669

Claim:
A combiner/divider circuit comprising: first, second, third, fourth, and fifth planar transmission lines, each of the first, second, third, fourth, and fifth transmission lines having a planar signal conductor and a planar first signal-return conductor disposed in spaced opposition to the signal conductor, the signal and signal-return conductors of the first, second, third, fourth, and fifth transmission lines having connection ends in a connection region, and the connection end of the signal conductor of the first transmission line being connected to the connection ends of the signal conductors of second and third transmission lines; a first via connecting the connection end of the signal conductor of the fourth transmission line with the connection end of the first signal-return conductor of the second transmission line; and a second via connecting the connection end of the signal conductor of the fifth transmission line with the connection end of the first signal-return conductor of the third transmission line.
