The AFI connector series is a board-to-board solution for RF applications, commonly used in military and broadband applications.

The AFI interface utilizes a proprietary two-piece configuration that allows for high misalignment compensation both axially and radially. This industry-leading float results in a maximum misalignment allowed by the system of .030” [0.8 mm] radial and .040” [1.0 mm] axial.

The interface is available in two configurations: 75 ohm with a performance of DC to 3 GHz, and 50 ohm with a performance of DC to 6 GHz.
