20090100491 | Signal Splitter Circuit - A signal splitter for reducing noise ingress and a cable television network incorporating such splitters. A signal splitter has an input and a plurality of outputs, where alternate outputs are connected to phase shifting devices. Prevention circuitry is provided for at least preventing the generation of intermodulation products in the phase shifting devices. The prevention circuitry is provided with a pre-connected filter in the form of a high-pass filter for stopping voltage peaks through reflection of the energy contained in the voltage peaks. | 04-16-2009 |
20100225412 | Signal Splitter - A signal splitter comprising an input and a plurality of outputs is provided, wherein alternate outputs are connected to phase shifting devices. The phase shifting devices preferably comprise phase shifting transformers and introduce a phase shift of 180°, so that noise components of alternate outputs are antiphase and cancel one another out almost entirely when the signals are summed. Also provided is a cable television network comprising a plurality of such signal splitters to ensure that noise ingress in upstream signals passing into the network is substantially reduced. | 09-09-2010 |

20090189709 | Signal splitter with improved transmisson line transformer - A splitter circuit for use in a CATV network. A signal input communicates with a first balun to supply two signal outputs, wherein the first balun is impedance matched to the impedance of the input using two or more additional baluns in parallel with each other. The additional baluns are transmission line baluns in parallel or series with resistive and/or capacitive and/or inductive components. | 07-30-2009 |
