The first switch has a transmission line connecting the antenna terminal and the input terminal; a diode having an anode connected to a first node between the transmission line and the input terminal, and a cathode connected to a second node; and a capacitor connected to the second node and a first power supply voltage. A first control terminal is connected to the first node via a first resistor and a first inductor. The first switch further includes a charging/discharging circuit connected to a second power supply voltage and the first control terminal and charging and discharging the capacitor from the second node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-frequency switch circuit and front-end circuit including same","description":"A high-frequency switch circuit includes a first switch configured to electrify or cut off connection between an antenna terminal and an input terminal, and a second switch configured to electrify or ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11489240","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.
