Abstract
Systems and methods for selecting, combining and duplexing signals in a communications network. Several configurations of diplexers and channel selectors are disclosed which use filters, combiners and splitters to select and combine which the signals to be either received or transmitted.
Claims25
A channel selector comprising:
- a first filter having a first terminal and a second terminal;
- a second filter having a first terminal and a second terminal, the first terminal being coupled to the first terminal of the first filter;
- a first single pole, single throw (SPST) switch having a first terminal and a second terminal, the first and second terminals being electrically connected when the switch is closed and electrically isolated when the switch is open, the first terminal being coupled to the second terminal of the first filter;
- a second SPST switch having a first terminal and a second terminal, the first and second terminals being electrically connected when the switch is closed and electrically isolated when the switch is open, the first terminal being coupled to the second terminal of the second filter;
- and
- a combiner/splitter having two isolation terminals and a common terminal, the first isolation terminal being coupled to the second terminal of the first switch and the second isolation terminal being coupled to the second terminal of the second switch.

A method of selecting signals from a combined signal, the method comprising:
- receiving a signal within a common port of a splitter;
- coupling the signal from a first isolation port of the splitter to a first switch and from a second isolation port of the splitter to a second switch;
- coupling an output from the first switch to a first terminal of a first filter;
- coupling an output from the second switch to a first terminal of a second filter;
- coupling a second terminal of the first filter to a common output port and to a second terminal of the second filter;
- and
- selecting signals from one of three frequency bands to be passed from the common port of the splitter to the common output port by selectively opening or closing the first and second switch.
