Abstract
A device for bi-directional amplification of data signals over power lines is disclosed. In one embodiment, the device includes a bandpass filter, a frequency converter and an amplifier. The bandpass filter filters out undesired frequencies and the frequency converter converts the frequency band of the data signals to a different frequency band. The output of the filter is provided to the amplifier for amplifying the frequency converted data signals for transmission over power line.
