  • Patent number: 9113187
    Abstract: Techniques for adding WiFi capabilities to a region may include installing WiFi access points in a cable television (CATV) system. For easier installation of the WiFi access points, a WiFi access point extension devices may be integrated into existing taps in the CATV system. The WiFi extended taps are able to provide radio frequency (RF)/CATV signals to subscribers, provide power to the respectively integrated WiFi access point, and maintain power to the coaxial transmission line during installation. During installation, the WiFi access point extension devices can be integrated into the CATV outdoor distribution plant without having to splice into an existing coaxial transmission line. The multiplicity of existing tap locations in CATV distribution plants makes the positioning of new wireless access points extremely versatile for the cable provider.

  • Publication number: 20150048897
    Abstract: A monolithic power splitter is used to split a pair of input differential signals into two pairs of output differential signals in the present invention. The monolithic power splitter has two input terminals to receive a pair of input differential signals, and it has two one-by-two power splitters integrated in one single chip to split a pair of input differential signals into two pairs of output differential signals with equal power. And, the monolithic power splitter has four output terminals to output two pairs of output differential signals. In one embodiment, the first one-by-two power splitter and the second one-by-two power splitter are made on the same surface of the substrate. In another embodiment, the first one-by-two power splitter and the second one-by-two power splitter are made on opposite surfaces of the substrate. The monolithic power splitter can be used as a power combiner based on the reciprocal property of the power splitter circuit.
