摘要： A power line communication device including a current path provided between a first terminal and a second terminal. A coupling circuit connected between the first and second terminals includes a first circuit of a first inductor connected in parallel with a first capacitor and a first resistor. A sensor is configured to sense a communication parameter of the coupling circuit. The communication parameter may be a resonance of the first circuit, the quality (Q) factor of the resonance, the bandwidth (BW) of the coupling circuit, the resistance of the first resistor, or the impedance of the first circuit. A transceiver is adapted to couple to the first and second terminal to transmit a signal onto the current path or receive a signal from the current path responsive to the parameter of the coupling circuit and a level of current in the current path sensed by the sensor.

摘要： A signal transmission device includes a signal side electrode; a first signal line connected to one side of the signal side electrode; a second signal line connected to the other side of the signal side electrode; a power source side electrode that forms a pair with the signal side electrode and is connected to the signal side electrode via an electronic component including at least an inductor component; and a capacitive coupling part that capacitively couples the power source side electrode to a ground wiring or a power source wiring. The first signal line, the signal side electrode, and the second signal line form a transmission path for transmitting an electric signal. The first signal line and the second signal line transmit power via the signal side electrode, the electronic component, and the power source side electrode.

摘要： A signal coupler (100) comprising: a main-transmission-line (114) that extends in a longitudinal direction within a substrate (102) between an input port and an output port; and a coupled-transmission-line (116) that extends in the longitudinal direction within the substrate (102) between a coupled port and a termination port. The coupled-transmission-line (116) is in a second layer (110). The main-transmission-line (114) comprises a first-portion (120) in a first layer (108), a second-portion (122) in a second layer (110), and a third-portion (124) in a third layer (112). At least part of the first-portion (120) is spaced apart from the coupled-transmission-line (116) in a depth direction. At least part of the second-portion (122) is spaced apart from the coupled-transmission-line (116) in the depth direction. At least part of the third-portion (124) is spaced apart from the coupled-transmission-line (116) in the depth direction.

摘要： Methods, apparatuses, and systems for verifying alignment of a compact antenna test range (CATR) are presented. A radio frequency (RF) profile may be generated based on test signals received by a reference antenna at a plurality of orientations. Phase and amplitude data of the RF profile may be used to determine whether the CATR is aligned properly.

摘要： A radiofrequency (RF) wireline communications system includes an interference filter for filtering interference noise at a cable interface that couples a cable of the system to functional circuitry. The interference filter includes a first termination resistance element coupled between a first cable conductor and a system ground, and a first termination reactance element coupled to the first termination resistance element. The first termination reactance element has a first termination reactance value selected to direct signals on the first cable conductor, having predetermined frequency characteristics, away from the system ground, and the first termination resistance element has a first termination resistance value selected as a pull-down resistance for interference signals having other than the predetermined frequency characteristics, that are not directed by the first termination reactance element away from the system ground, to cause the interference signals, having other than the predetermined frequency characteristics, to propagate to the system ground.
