Problems solved by technology

However, in such ferrite core splitters, the bandwidth expansion and / or the addition of intermediate circuits both increases input-to-output loss, and provides high isolation in the output-to-output MoCA band with the Notches that can cause loss of in-band signal

Embodiment Construction

[0022] Embodiments of the present disclosure may provide a reflection-free home network adapter (RNA) that allows a home network device or splitter to couple to another device or splitter to efficiently couple home network signals (e.g., in MoCA bandwidth) circuit. RNA may also provide (eg, complete) isolation from non-home network signals (eg, CATV access network signals and / or noise). RNA can provide isolation in more desirable ways than using reflective filters, so in some embodiments reflective filters can be omitted. RNA creates paths that absorb, attenuate, or terminate CATV access signals (i.e., non-domestic signals) so that they are not reflected at the input or transmitted from output to input, thereby preventing these signals from generating noise back into the network to which they are coupled. interfere with reflection. The coupled network is a "CATV access network", which is coupled to the output of an access network device (such as a MoCA amplifier or splitter)...

Abstract

A system includes a cable television (CATV) device configured to transmit and receive signals in a first bandwidth and to transmit and receive signals in a second bandwidth. The first bandwidth is higher than the second bandwidth. The system also includes a home network splitter including an input, a common node, and a plurality of outputs. The input is configured to connect to the CATV device. The system also includes a reflectionless home network adapter (RNA) configured to connect to and between the input and the common node. The RNA allows signals in the first bandwidth to pass from the input to the plurality of outputs and from the plurality of outputs to the input. The RNA prevents signals in the second bandwidth from passing from the input to the outputs, from the outputs to the inputs, or both.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 618,224, filed January 17, 2018, and U.S. Provisional Patent Application No. 62 / 684,579, filed June 13, 2018. The entire contents of both applications are incorporated herein by reference. Background technique [0003] Typical traditional splitters or power splitters used in Cable Television (CATV) networks and Multimedia over Coax Alliance (MoCA) networks primarily use ferrite transformers to provide a broadband circuit with low input-to-output loss and high output to output isolation. These ferrite splitter circuits are constructed in many different ways to include additional intermediate circuitry for achieving acceptable home performance for CATV bandwidths (eg 5MHz to 1002MHz) and MoCA bandwidths (eg 1125MHz to 1675MHz). However, in such ferrite core splitters, the bandwidth expansion and / or the addition of intermediate circuits both in...
