Abstract:
1. A high-speed feedthrough (HSFT) operative to transmit a signal, having a highest frequency of at least 10 GHz corresponding to a shortest free space wavelength, between a first interface location and a second interface location that are separated by a vertical distance of at least a millimeter, and separated by a horizontal distance, the HSFT comprising: a substrate structure comprising multiple stacked layers; and an RF transmission line connected through the substrate structure between the first and second interface locations operative to transmit the signal between the first and second interface locations, the RF transmission line comprising a series of sequentially connected horizontal and vertical conductors; the horizontal conductors having lengths less than half of an effective wavelength that corresponds to the shortest free space wavelength of the signal when transmitted through the HSFT, and the vertical conductors having heights less than one quarter of the effective wavelength; thereby spanning the horizontal and vertical distances between the first and second interface locations in a stairs-like shape through the layers of the substrate structure.
