Abstract
An enabling circuit for use in a wideband signal distribution system is provided. The circuit includes a input port which receives a baseband source signal, a transmission path between the input port and the output port, an impedance matching device, and a power source connected to the impedance matching device which combines a biasing signal with the input signal in order to operate a diode switch which is connected to the output to the impedance matching device and located in a distribution unit of the system.
