Abstract: An attenuator arrangement comprising at least a first attenuation path configured to couple between a signal processing chain, SPC, and a measurement apparatus; said SPC comprising a first and second SPC terminal, said SPC configured to apply one or both of a gain and phase change on a signal passed between the SPC terminals; said measurement apparatus configured to measure one or both of the gain and the phase change applied by SPC by coupling to and receiving signals from said SPC terminals; wherein one of said first SPC terminal and said second SPC terminal is coupled to the measurement apparatus through said first attenuation path; and wherein the at least first attenuation path of the attenuator arrangement is configured to provide, selectively, for attenuation of the signal to the measurement apparatus to make the signal power of the signals from said SPC terminals more equal.

Abstract: 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.
