Abstract:
1. A transmission system for providing RF signals, power and control signals to a device, comprising: at least one bias network within the device, said at least one bias network being capable of being connected to at least one respective RF coaxial cable to receive respective multiplexed RF signals and controls signals, said at least one bias network being further capable of de-multiplexing the RF signals and control signals; at least one control line being connected to a respective one of said at least one bias network to receive a respective one of the de-multiplexed control signals; control circuitry within the device connected to said at least one control line to receive all of the de-multiplexed control signals, said control circuitry being configured to control the state of the device based on the states of the received de-multiplexed control signals; and a passive network within the device connected to said at least one control line to receive all of the de-multiplexed control signals and provide power to said control circuitry based on the state of each of the de-multiplexed control signals.
