Abstract
High port-to-port RF isolation for a test socket in a production RF test environment is achieved by establishing a coaxial-type connection between the test socket and the device under test (DUT). This coaxial-type connection results by at least partially surrounding each port of the DUT with a ground seal connected to RF ground connection. In one embodiment, the ground seal is a metallic base plate of the test socket which surrounds the RF connection to the DUT.
