26. A method comprising:
establishing a frequency-converting coupling between at least one antenna of a plurality of antennas of a device under test (DUT) and a plurality of waveguide transitions arranged at different positions of a dielectric waveguide slab to cause a frequency-converting coupling between the plurality of antennas and a plurality of radio frequency components configured to perform at least one of transmit radio signals or receive the radio signals, wherein the dielectric waveguide slab comprises a plurality of frequency converting structures, wherein a frequency conversion is performed on radio signals received by the plurality of frequency converting structures arranged in at least one of in the dielectric waveguide slab or on the dielectric waveguide slab; and
using the frequency-converting coupling between the plurality of antennas and the plurality of radio frequency components to characterize the DUT.
