.DataSheet.co.kr APPLICATION NOTE APN1006: A Colpitts VCO for Wideband (0.95- 2.15 GHz) Set-Top TV Tuner Applications Introduction Modern set-top DBS TV tuners require high-performance, broadband voltage control oscillator (VCO) designs at a petitive cost. To meet these goals, design engineers are challenged to create high-performance, low-cost VCOs. The Colpitts oscillator is a traditional design used for many VCO applications. Designing a broadband Colpitts oscillator with coverage from 1- 2 GHz requires the selection and interaction of an appropriate varactor diode for its resonator. This application note describes the design of a broadband Colpitts VCO that incorporates the...
