Abstract
A system and method for managing distribution of wideband radio frequency signals includes detecting an impedance signature of a device connected at the end of transmission medium. A switch is opened to apply a wideband radio frequency signal to a transmission medium for distribution. A biasing voltage can be applied to the transmission medium based on the detected impedance signature. A signal conditioning circuit is selected based on the amplitude of the biasing voltage, and the wideband radio frequency signal is distributed to an output device.

A system for managing distribution of wideband radio frequency signals, comprising:
- a distribution unit having an input port and an output port for distributing a wideband radio frequency signal over a transmission medium, and an impedance signature detecting device for detecting an impedance signature of a system interface device, wherein the system interface device is connected at a termination point of the transmission medium;
- a first processor connected to the distribution unit and the impedance signature detecting device for actuating a switch allowing distribution of the wideband radio frequency signal over the transmission medium based on the impedance signature detected by the impedance signature detecting device, and for signaling a direct current biasing device to apply a biasing direct current voltage to the transmission medium, wherein the biasing voltage amplitude is based on the detected impedance signature;
- and
- a second processor located at the system interface device for detecting the biasing voltage, and for actuating a signal conditioning device based on the amplitude of the biasing voltage that selectively conditions the wideband radio frequency signal for output to an output device connected to the system interface device.
