ABSTRACT:
An impedance transforming power divider/combiner includes a first transmission line (60) with a first terminal (65) and N transmission line fingers (65, 66, 68, 70) terminating in N transmission line finger ends. N transmission lines (28, 38, 48, 58) having N first and second ends are positioned in close proximity to the N transmission line fingers (65, 66, 68, 70) in one-to-one correspondences. The N second ends of the N transmission lines (28, 38, 48, 58) are coupled through N individual impedances (20, 30, 40, 50) to N terminals (25, 35, 45, 55). If signal power is provided to the first terminal (64), the signal power is divided into N signal power outputs at the N terminals (25, 35, 45, 55). If signal power is provided to the N terminals (25, 35, 45, 55), a combined signal power results at the first terminal (65).
