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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
