Extended Characterization for the MAX2112/MAX2120 Satellite Tuners
Abstract: This application note presents typical measured data for the MAX2112/MAX2120 direct-conversion satellite tuners. The data illustrate the tradeoffs between RF and baseband gain control. Voltage gain, P1dB, noise figure (NF), and carrier-to-noise ratio (CNR) are shown across the RF and baseband gain-control ranges. Through understanding these tradeoffs, one can optimize an application's desired dynamic range.
