The quasi-coaxial line has: a central conductor being a vertical through hole via that connects between a metal pattern formed on an upper surface of the uppermost layer and a metal pattern formed on a lower surface of the lowermost layer; and outer conductors being a plurality of interlayer vias that are circularly arranged around the central conductor and connect between two or more layers. Whole or a part of the vertical through hole via is substituted by a capacitor structure formed of conductor pads facing each other without any via."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-frequency package","description":"In a multilayer substrate, a quasi-coaxial line is formed as a structure for transmitting a high-frequency signal generated by a mounted high-frequency device from an uppermost layer to a lowermost la","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9591756","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
