In order to provide the chips required for this change in the landscape, there will be a large number of changing requirements in wafer test that come out of these architectural requirements. Form Factor partnered with Intel to investigate these changes, and tested one such example of a new test methodology.

In a joint collaboration with Intel to develop a test methodology for their 5G RF-SoC devices, OTA testing was explored because it could provide simpler power combining in the dense RF-SoC device layouts. A test device was selected by Intel, and a membrane was designed for this device that then included three different measurement paths.
