1. A test set-up for testing a system-in package (SiP) with an integrated antenna, the test set-up comprises:
- a carrier with an RF probe antenna arranged thereon; and
a test socket with resilient electric contacts, the test socket being mounted on the carrier and providing an electric contact to interconnects of the SiP when placed on the test socket,wherein the test socket has an opening which is arranged superjacent to the RF probe antenna, the opening providing a passage through the test socket such that electromagnetic radiation emanating from the integrated antenna included in the SiP passes through the opening and reaches the RF probe antenna.

6. A system for testing a system-in package (SiP) with an integrated antenna, the system comprises:
-
a wafer chuck configured to receive the SiP; and an automatic test equipment including a carrier with an RF probe antenna arranged thereon and a test socket with resilient electric contacts mounted on the carrier; wherein the wafer chuck is configured to place the SiP on the test socket so that the resilient electric contacts of the test socket provide an electric contact to interconnects of the SiP, and wherein the test socket has an opening which is arranged superjacent to the RF probe antenna, the opening providing a passage through the test socket such that electromagnetic radiation emanating from the integrated antenna included in the SiP passes through the opening and reaches the RF probe antenna. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method for testing a system-in package (SiP) with an integrated antenna, the method comprises:
-
placing the SiP on a test socket using a wafer chuck, the test socket being attached on a carrier and including resilient electric contacts that provide an electric contact to interconnects of the SiP; using an RF probe antenna mounted on the carrier to obtain near-field measurements of an electromagnetic field emanating from the integrated antenna, the electromagnetic field extending through an opening in the test socket that is arranged superjacent to the RF probe antenna; and calculating far-field data from the near-field measurements. - View Dependent Claims (13, 14, 15)
