Antennas and RF electronics are becoming more integrated with millimeter-wave frequencies. The presence of antennas in phased-array systems changes the behavior of the RF electronics, which means that traditional RFIC metrics now need to be tested over-the-air, and for many different beamforming settings. This requires new types of testing methods. In this talk, we explain the challenges of testing over-the-air, and present new techniques for measuring metrics such as noise figure, out-of-band emissions, radiated power spectrum, and field distribution in advanced, highly-integrated mmWave devices.
