Abstract: A frequency plan is provided for particular use in a transceiver. Advantageously, a single oscillator may be used to generate desired frequency signals. 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. In one exemplary embodiment, multiple signals having different frequencies may be transmitted over the same cable due in part to the generated frequency separation between the signals. In another exemplary embodiment, multiple signals may be transmitted over multiple cables. Additionally, multiple signals over one or more cables may be transmitted at or below 3 GHz.

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.

The method and system each, respectively, utilize the apparatus to improve the power and reliability of transmitted communication signals.

Abstract: A wide bandwidth frequency multiplier (48) multiplies a first frequency of an input signal (52) to generate an output signal (54) having a second frequency. The multiplier (48) includes first stage doubler (56). The doubler (56) includes a lumped element power splitter (62), a push-push amplifier (80), and a combining junction (96). The power splitter (62) splits the input signal (52) into first and second signals (70, 72) that are balanced in phase. A series resistive element (86) maintains amplitude balance between the first and second signals (70, 72). First and second feedback circuits (166, 184) are integrated with first and second transistors (164, 182) so that the push-push amplifier (80) operates over wide bandwidth. In addition, the multiplier (48) includes a second stage doubler (58) configured similar to the first stage doubler (56) for producing an output signal (54) that is quadruple the frequency of input signal (52).
