A device for switchably routing down-converted radio frequency (RF) signals from a plurality of inputs to a plurality of outputs, and a method of operating the same. The device includes a respective switch for each output. The device also includes an interconnect arrangement. The interconnect arrangement includes a respective transmission line for each input. Each transmission line includes a plurality of branches for routing a down-converted RF signal received at the input of that transmission line to the switch of each output. The switch of each output is operable selectively to connect one of the transmission lines to its output. The interconnect arrangement also includes a plurality of cross-over points at which two of the branches cross over each other.
