Abstract
This letter addresses the importance of evaluating the radio-frequency immunity (RFI) absolute level at high-speed interfaces in a smart phone product. In this letter, a practical radio-frequency coupling flexible-printed circuit (FPC) design was introduced. It can be adapted to a device under test (DUT) easily, comparing the high-speed RFI level margin across different DUTs. The proposed evaluation method has been tested, and results are provided for consideration.
