Abstract: Devices and methods for testing microelectronic assemblies including wireless communications are disclosed herein. For example, in some embodiments, a wireless testing system may include a radio frequency (RF) shielded chamber; a device under test (DUT) in the RF shielded chamber, wherein the DUT includes an array of first antenna elements; a testing apparatus in the RF shielded chamber including an array of second antenna elements at a first surface of a substrate to receive a test signal from the DUT, wherein a distance between individual second antenna elements and an adjacent second antenna element is at least half of a wavelength of the test signal, and wherein a distance between the first antenna elements and the second antenna elements is within a near-field region; and an array of electrical switches, wherein an individual electrical switch is coupled to a respective individual second antenna element.

Abstract: A coaxial radio frequency adapter and method are disclosed. An adapter has a tapered signal pin and a tapered ground sleeve to maintain a consistent impedance and minimize reflections while connecting two elements having different dimensions. A method employs an adapter to characterize losses in a system for evaluating a device under test.
