ABSTRACT:
A frequency plan is provided for particular use in a transceiver. Advantageously, a single oscillator may be used to generate desired frequency signal. One or more power splitters receive the signal and equally divide the signal into first and second signals having a frequency substantially equal to the original. Multipliers on each arm of the transceiver receive a signal and increase the frequency of the signal. Ultimately, multiple signals having different frequencies may be transmitted over the same cable due in part to the generated frequency separation between the signals. In one particular aspect, the frequency plan provides a two-thirds relationship between the frequencies of the multiple signals.
