Broadband Colpitts VCO for TV Tuner


Posted on Feb 4, 2014

The high performance of modern set-top DBS TV tuners require broadband voltage control oscillator (VCO) designs at a competitive cost. To realize these goals, design engineers are challenged to create high performance, low-cost VCOs. The traditional design of Colpitts oscillator is 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 design describes a broadband Colpitts VCO that incorporates the SMV1265-011 varactor diode.
