ABSTRACT:
A power splitter is disclosed for dividing radio frequency (R.F.) power applied to an input terminal equally among n number output terminals, where n.gtoreq.2 and is an integer, irrespective of the impedances at the input or at the output terminals. The power splitter utilizes n number .lambda./4 inner conductors disposed in a .lambda./4 housing, which provides a common electromagnetic shield. The input terminal is formed by connecting together the first end of each inner conductor, the first ends being present at a first opening in the housing. The second ends of the inner conductors, which are all present at a second opening in the housing, are connected together outside the housing by (n-1) number .lambda. lines so as to form an electrical wheel. Each end at the second opening is an output terminal of the power splitter. A power combiner is disclosed for summing at an output terminal R.F. power applied to n number input terminals, where n.gtoreq.2 and is an integer, irrespective of the impedances at the input or output terminals. The power combiner utilizes n number .lambda./4 inner conductors disposed in a .lambda./housing, which provides a common electromagnetic shield. The first end of each inner conductor present at a first opening in the housing is an input terminal. The output terminal is formed by connecting together the second ends of each inner conductor present at the second opening in the housing.
