Also included is at least one coupling structure coupled between the second port of the first resonator and the third port of the second resonator, wherein the coupling structure has a coupling control input for varying a coupling coefficient between the first resonator and the second resonator such that an RF signal transfer between the first port of the first resonator and the fourth port of the second resonator is controllably variable between 5% and 95%."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio frequency (RF) front-end without signal switches","description":"Disclosed is an RF front-end with improved insertion loss having at least a first resonator with a first port and a second port and at least a second resonator having a third port and a fourth port, w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9787353","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.
