Abstract: A power splitter/divider may be used with a paralleled amplifier. The power splitter/divider includes a common port and a distribution structure for distributing equal-amplitude samples of the applied signal from the common port to four cascades of artificial transmission lines. The impedances of the sections of artificial transmission line are stepped, in order to provide an impedance transformation between the individual ports and the impedance presented to the common port. When there are four cascades, each presents an impedance of 200 ohms to the common port, for operation in a 50-ohm system. Each artificial transmission line of each cascade includes at least two planar, spirally disposed elongated conductors, spaced to provide mutual coupling between turns. In at least some of the artificial transmission lines, discrete capacitors aid in forming pi sections of transmission line.
