The transformer comprises a primary winding with a terminal for connecting to an antenna, and a secondary winding comprising a first terminal, a second terminal and a third terminal located between the first and second terminals. The power amplifier is connected to the secondary winding, the low-noise amplifier is connected to both the primary and secondary windings and the voltage control circuit portion is connected to the third terminal of the secondary winding. The voltage control circuit portion applies a first voltage to the third terminal when the transceiver operates in the transmission mode and applies a second, different voltage when the transceiver operates in the reception mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio front-end","description":"A circuit portion for a radio transceiver comprises: a power amplifier for use when the transceiver operates in a transmission mode, a low-noise amplifier for use when the transceiver operates in a re","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11990925","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.
