Abstract: Space transformers configured to be utilized in a probe system to facilitate electrical communication with a device under test (DUT), probe systems that include the space transformers, and related methods are disclosed herein. The space transformers include a dielectric body, a plurality of first electrical contacts supported by the dielectric body, and a plurality of second electrical contacts supported by the dielectric body. The space transformers also include an electrically conductive radio frequency (RF) signal-modifying trace. The space transformers further include an RF electrical signal-modifying structure in electrical communication with the electrically conductive RF signal-modifying trace. The RF electrical signal-modifying structure is configured to receive the RF electrical signal from an input region of the electrically conductive RF signal-modifying trace and to discharge a modified RF electrical signal to an output region of the electrically conductive RF signal-modifying trace. The RF electrical signal-modifying structure includes a coupler.
