In a specific region in a low-output region and close to a high-output region, the variable gain adjustment section (114) adjusts the power level of the phase signal to a predetermined upper-limit level, and the amplitude signal driving section (220) adjusts a gain of the power amplifier (130) to obtain a desired output power level."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmission circuit","description":"A transmission circuit according to the present invention includes: an amplitude signal driving section (220) that generates a control voltage based on an amplitude signal in a high-output mode, and g","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8532591","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.
