A production interface solution that enables OTA testing of a 60GHz UltraGig single-chip integrated Antenna in Package (AiP) has been delivered to a customer by Multitest. The solution integrates the xWave OTA Contactor with xWave patch antenna in the MT2168XT leadbacker.

This integration of an OTA patch antenna into the leadbacker of a production pick and place handler is believed to be the first in the industry.

This solution offers a reliable production solution testing an AiP device with 60 GHz RF signals both radiating out of an antenna array in the lid and connected through the ball grid array.

It leverages knowledge on RF signal integrity and the ability to integrate this interface solution into a state-of-the art test handler for high volume production.

In this application an OTA manual actuator clone of the handler leadbacker was also provided to accelerate test program debug activities.

xWave OTA Contactors have also been used for testing of 76-81GHz AiP automotive radar devices and are being designed for 5G applications at 28 GHz and 39 GHz. Radiation patterns and directivity vary by application out the top, sides and/or bottom of the AIP.
