SL2015
Full Band Satellite Tuner
Advance Information
Supersedes April 1997 version, DS4548 - 2.1
DS4593 - 3.2 February 1998
The SL2015 is a fully integrated mixer oscillator 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 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 SL2015 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.
