    Abstract: A phased array transmitter includes a plurality of signal couplers arranged to receive a radio frequency (RF) input signal, and a plurality of RF transmitters coupled to the signal couplers. Each RF transmitter includes a radiating element, a chip and a phase shifting circuit. The radiating element is arranged to receive a plurality of electrical signals to produce an RF output signal. An amplifier circuit of the chip is configured to amplify the RF input signal to generate a plurality of amplified signals at a plurality of output terminals, respectively. The phase shifting circuit is located outside the chip, and coupled to the output terminals and the radiating element. The phase shifting circuit is arranged to phase shift the amplified signals, and accordingly generate the electrical signals fed to the radiating element. Respective phase shifting circuits and respective radiating elements of the RF transmitters are formed on a same substrate.

    Abstract: A near-field testing apparatus for testing a device under test having an array of transmitter antennas is provided. The near-field testing apparatus includes a frame structure and a receiver circuit. The frame structure defines an array of grid sections, and is arranged for receiving the array of transmitter antennas at a first side of the array of grid sections. A periphery of each grid section at the first side surrounds a plurality of transmitter antennas in the array of transmitter antennas. The grid section is arranged to guide respective electromagnetic signals emitted by the transmitter antennas from the first side to a second side of the array of grid sections. The receiver circuit, disposed at the second side of the array of grid sections, is arranged to couple the electromagnetic signals out of the grid section.
