Abstract:
1. An electronic assembly comprising: an integrated circuit package configured to transmit and receive radio-frequency signals through an cable acceptor; and a flexible interconnect cable having a first end coupled to the cable acceptor, the flexible interconnect cable comprising: a flexible dielectric layer, wherein a thickness of the flexible dielectric layer depends on one or more of the following: flexibility, length, number of conductive and dielectric layers or a desired transmission line impedance of the flexible interconnect cable: a first and a second longitudinal signal conductive traces on a first surface of the flexible dielectric layer, the first and the second longitudinal signal conductive traces being physically adjacent and electromagnetically coupled to each other, forming a pair of conductive traces carrying complementary differential radio-frequency electrical signals; a first ground conductive trace adjacent and electromagnetically coupled to the first longitudinal signal conductive trace; a second ground conductive trace adjacent and electromagnetically coupled to the second longitudinal signal conductive trace, and wherein a first portion near the first end of the flexible interconnect cable is configured to have a first line width and spacing of the first and the second longitudinal signal conductive traces, a first signal-to-ground distance and a first width of the first and the second ground conductive traces, the first line width and spacing of the signal conductive traces being adapted to match with the corresponding width and spacing of a plurality of conductive pads on the acceptor.
