A newly filed patent (Publication Number: US20240039578A1) describes a cable network system designed to enhance duplex frequency range communication bidirectionally. The system includes a first amplifier device with various components such as shaping circuits, amplifiers, and splitters to receive, equalize, amplify, and transmit signals in both directions without the need for a diplex filter. The second amplifier device in the system is configured similarly to the first but operates in the opposite direction, ensuring bidirectional communication at an enhanced duplex frequency range without amplifying signals in the wrong direction. The system is tailored for cable network signals, with the first direction being downstream from a network provider to a subscriber and the second direction being upstream from the subscriber to the network provider.

Furthermore, the patent details an amplifier device specifically designed for bidirectional communication at an enhanced duplex frequency range within a cable network system. This device includes shaping circuits, amplifiers, and splitters to condition and transmit signals in both directions simultaneously without the need for a diplex filter. The system operates within a frequency range of about 5 MHz to 650 MHz, ensuring full duplex communication without limitations of a half-duplex frequency range. The amplifier device is capable of amplifying signals in either the downstream or upstream direction, with separate paths for amplification and non-amplification to ensure efficient signal processing and transmission.
