The second impedance matching network has at least a first connection path to the reference terminal, a second connection path to the second power amplifier and a third connection path to the common impedance matching network. The second impedance matching network also includes a first impedance switch configured to open the first connection path responsive to the second power amplifier being put into an OFF state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RX-TX switch with two power amplifiers","description":"An RF front end circuit has a common impedance matching network connected to an output terminal, a first power amplifier arranged to drive power to the output terminal through the common impedance mat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9590689","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.
