Abstract
Many advanced signal receiving devices include more than one tuner. An apparatus is described that includes a first circuit operating as a first portion of a signal attenuator, a second circuit operating as a second portion of the signal attenuator and outputting a first differential output signal, and a third circuit also operating as the second portion of the signal attenuator and outputting a second differential output signal. A method is described including receiving a signal, splitting the received signal to produce a first output signal and a second output signal, the splitting being performed using a differential signal format and further being performed using only at least one of a resistor, capacitor, and inductor, and outputting the first output signal in a differential signal format and the second output signal in a differential signal format.
