SL1925
Satellite Zero IF QPSK Tuner IC
Preliminary Information
Description
The SL1925 is a wideband quadrature converter operating
from 950 to 2150 MHz, intended primarily for application
in satellite tuners.
The device contains all elements necessary, with the
exception of local oscillator sustaining network, to fabricate
a high performance I(n-phase) & Q(uadrature) phase
splitter and downconverter optimised for systems
containing RF AGC gain control. The device allows for
systems containing higher power analog interferers. For
most applications RF tunable filtering is not essential.
The SL1925 is optimised for use with a low phase noise
synthesiser, a range of which are available from Mitel
Semiconductor. This will form a complete front end tuner
function for digital satellite receiver systems utilising DSP
derotation recovery.
The device includes a very high signal handling front end
with AGC, this provides for gain control, reference local
oscillator with output buffer, phase splitter with I and Q
mixers and baseband buffer amplifiers with external
interstage filtering.
Features
