ABSTRACT:
An impedance transforming three-port power divider/combiner includes first, second, and third lumped elements (e.g. 54, 55, and 56). The first lumped element (54) couples the first port (51) and electrical ground. The second lumped element (55) couples the first and second ports (51 and 52), and the third lumped element (56) couples the first and third ports (51 and 53). A resistor (59) is coupled between the second and third ports (52 and 53). Capacitors (57 and 58) couple the second port (52) and the third port (53) to electrical ground. A signal input to the first port (51) results in identical divided output signals at the second and third ports (52 and 53). Signals input to the second and third ports (52 and 53) result in a combined output signal at the first port (51).
