摘要： A flexible, reconfigurable, power efficient transmitter device and method is provided. In one embodiment, the method includes receiving outbound data and determining a mode of operation. When operating in a first mode the method may include modulation mapping the outbound data according a modulation scheme to provide first modulation mapped digital data, converting the first modulation mapped digital data to an analog signal that comprises an intermediate frequency (IF) analog signal, upconverting the IF analog signal to produce a first modulated radio frequency (RF) signal based on a local oscillator signal, amplifying the first RF modulated signal to produce a first RF output signal, and outputting the first RF output signal via an isolator. In a second mode of operation method may include modulation mapping the outbound data according a modulation scheme to provide second modulation mapped digital data, converting the second modulation mapped digital data to a first digital baseband signal, conditioning the first digital baseband signal to provide a first analog baseband signal, modulating one or more carriers with the first analog baseband signal to produce a second modulated RF signal based on a local oscillator signal, amplifying the second RF modulated signal to produce a second RF output signal, and outputting the second RF output signal via the isolator. The digital baseband signal may comprise an in-phase (I) digital baseband signal and a quadrature (Q) baseband signal.

摘要： A passive bypass device for providing a data path around a power meter is provided. The device may be communicatively connected to two low voltage power line energized conductors on a first and a second side of a power meter. The energized power line conductors conduct both the data signals and the power. The bypass device includes a filter that causes the power to pass through the power meter while allowing the data signal to pass around the power meter thereby providing a substantially non-attenuated data signal path. The bypass device may include a first and second data path for the first and second energized conductors and with each path having a high pass filter and a fuse communicatively connected to its respective energized conductor on each side of the power meter.

摘要： A power supply of the present invention comprises a transducer having a transducer and a voltage regulator. The transducer is coupled to an electrically non-conductive medium, which may be a light pipe. The electrically non-conductive medium is coupled to a non-electrical energy source such as a light source and the non-electrical energy source communicates energy to the transducer via said electrically non-conductive medium. The transducer converts the received light energy to electrical energy, which is supplied to a voltage regulator. The voltage regulator has a regulator ground, regulator output, and regulator input. The regulator input is electrically coupled to the transducer output and the regulator ground is electrically coupled to a live conductor of a medium voltage power line. The regulator output therefore provides an output voltage that is ground referenced to the live conductor of the medium voltage power line.
