Abstract
A frequency translation system includes first and second translational switches, and a signal bus coupled therebetween. The first translational switch includes one or more inputs configured to receive a respective one or more first input signals, a first plurality of outputs, and a second plurality of outputs. The second translational switch includes one or more inputs configured to receive a respective one or more second input signals, a first output, and a second output. The signal bus, coupled between the first and second translational switches, includes (i) a first bus line coupled to a first one of the first plurality of outputs of the first translational switch, and to the first output of the second translational switch, and (ii) a second bus line coupled to a first one of the second plurality of outputs of the first translational switch, and to the second output of the second translational switch.
