Publication number: 20250038460Abstract: A high frequency cable assembly with a plug connector terminating shielded cables via cable termination assemblies mounted to a paddle card. Cable termination assemblies provide paths for ground current between the cable shield and paddle card providing low insertion and return loss and crosstalk at frequencies up to at least 53 GHz, which supports data rates of 224 Gbps and above. Disclosed features of the cable termination assemblies may be used alone or in combination and include: termination of a row of cables, structures configured based on angle of arrival of cables to the cable termination assembly, ground members that align with individual cables, and upper and lower ground members coupled to the cable shield and ground structures of the paddle card that at least partially encircle signal paths outside the cable shields. The upper and lower ground members provide ground current paths paralleling those signal paths with substantially uniform spacing.Type: ApplicationFiled: July 25, 2024Publication date: January 30, 2025Applicant: Amphenol CorporationInventors: Khwajahussain Gadwal Mohammed, Jose Ricardo Paniagua, Joseph Passarelli

Publication number: 20240055785Abstract: A cable assembly comprising a connector with a termination that enables high density and high signal integrity. Shields of cables are terminated to a paddle card via a conductive structure attached to a surface of the paddle card. The signal conductors of the cables are terminated to pads on the paddle card that are exposed within openings of the conductive structure. Such a structure creates a ground structure per cable that provides low insertion loss and low crosstalk, even when multiple cables are aligned side by side and terminated in one or more rows. The cables may be drainless, enabling a large number of cables, such as eight cables, to be packed within the width of a paddle card specified in high density standards such as QSFP-DD or OSFP. The cables may nonetheless have large diameter signal conductors, enabling 2.5 or 3 meter assemblies with less than 17 dB insertion loss.Type: ApplicationFiled: July 17, 2023Publication date: February 15, 2024Applicant: Amphenol CorporationInventors: Mark M. Ayzenberg, Khwajahussain Gadwal Mohammed, Erdem Matoglu, Catalin Muntean
