Abstract
Apparatus and methods for electronic testing using beamforming integrated circuits (ICs) as impedance tuners are disclosed herein. In certain embodiments, an electronic testing setup for a device-under-test (DUT) includes a radio frequency (RF) coupler including a through line connected to an output of the DUT, a first coupled line coupled to the through line, and a second coupled line coupled to the through line. Additionally, the electronic testing setup includes a beamforming IC including a first transmit channel having an output connected to the first coupled line, and a second transmit channel having an output connected to the second coupled line. A gain and a phase of the first transmit channel and a gain and a phase of the second transmit channel are each controllable to provide impedance tuning at the output of the DUT.
