The control circuit is arranged to successively apply, during the same UWB pulse, a first gate voltage turning the transistor on with first internal resistance value for a first part of duration T, a second gate voltage that turns the transistor on with second internal resistance value, different from the first, for a second part of duration T. These internal resistances cause the oscillation to be attenuated differently for duration T of the pulse, allowing the spectrum of the pulse to maintain it within the spectral templates imposed by the radio communication standards."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"UWB pulse generator","description":"An ultra-wideband pulse generator, for radio communication at frequencies of 2 to 11 GHz comprises an oscillator providing an output signal at carrier frequency F0 followed by a radiofrequency switchi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847811","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.
