The new concept of RF Interconnect presented in this paper is aimed at replacing conventional interconnections in digital circuits. The study was, thus, focused on the transmission channel composed of contactless transitions. After a brief recall of the theory, an RF interconnection was modeled through use of multiplexing digital CDMA and amplitude modulation and characterized by using a co-simulation tool. The frequency response of a radiofrequency channel and the signal forms observed along the transmission system are presented to highlight the capabilities of this RF interconnect.
