SL2017

SL2017 Full Band Satellite Tuner Preliminary Information DS4889 - 1.2 may 1998 The SL2017 is a fully integrated mixer with output AGC, intended primarily for application in satellite tuners, where it downconverts the first high IF from the outdoor unit to the second IF for data demodulation. The device contains a low noise RF input amplifier and mixer functioning to 2.15GHz, an integrated low phase noise local oscillator buffer and an AGC IF output buffer amplifier. The IF signal is available at one of two outputs selected by the IF-OP-SEL input. The signal handling of the SL2017 is sufficient to greatly simplify or remove the requirement for input AGC with appropriate image filtering in full band systems, or to remove the requirement for band limit filtering with appropriate AGC in half band systems.
