The first transfer function and second transfer function provide a first passband and a second passband, respectively. The first transfer function also has a stopband provided within the second passband of the second transfer function due to the filtering circuitry including a first parallel resonant circuit provided in series in a first filter path being weakly coupled to a second parallel resonant provided in shunt with respect to a second filter path. The weak coupling between the first parallel resonant circuit and the second parallel resonant circuit thus naturally provides a stopband in the first transfer function within the second passband of the second transfer function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiplexers using weakly-coupled networks in RF front end circuitry","description":"Multiplexing circuitry is disclosed that includes filtering circuitry, which provides a first transfer function between a common port and a first port and a second transfer function between the common","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9761367","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.
