Abstract: Methods and apparatus are disclosed for near field radio-frequency (RF) testing of devices, particularly user equipment (UEs) capable of millimeter-wave (mmWave) transmissions. An exemplary test apparatus is described that uses a transducer to facilitate near field over-the-air testing of UEs in the mmWave transmission band. The transducer may be an orthomode transducer and may include a dual-polarity port positioned in the reactive near field of an antenna of a device under test (DUT). For UE signal transmission tests, the orthomode transducer splits test signals received from the antenna of the DUT via the dual-polarity port into a pair of single-polarity RF signals. The single-polarity RF signals are separately fed through a pair of waveguide-to-coaxial adaptors into separate coaxial cables, which feed coaxial transmission versions of the single-polarity RF signals to test equipment for analysis. UE signal reception tests are also described that utilize the same or different orthomode transducer.
