Abstract :
Development of digital satellite L-band tuners is taking place under pressure to reduce costs. Direct conversion is attractive, as it reduces component count. There is no SAW filter and the absence of an image means the front-end tracking filter is greatly simplified. This IC shows feasibility of direct conversion for DBS, testing solutions to the issues: wide dynamic range, VCO-RF interactions and broadband quadrature accuracy.
