Abstract
A multichannel splitter formed from 1 to 2 splitters. An input terminal of a first 1 to 2 splitter defines an input of the multichannel splitter. The 1 to 2 splitters are electrically series-connected. First respective outputs of the 1 to 2 splitters define output terminals of the multichannel splitter.
Claims20
A multichannel splitter having an input and a plurality of outputs, the multichannel splitter comprising:
- a first 1-to-2 splitter that includes an input terminal that serves as the input of the multichannel splitter and a first output that serves as a first output of the multichannel splitter;
- a second 1-to-2 splitter that includes an input terminal coupled to a second output of the first 1-to-2 splitter and a first output that serves as a second output of the multichannel splitter;
- and
- a third 1-to-2 splitter that includes an input terminal coupled to a second output of the second 1-to-2 splitter and a first output that serves as a third output of the multichannel splitter.
