Features

Ordering Information

SL1925/KG/NP2S (Tubes)

SL1925/KG/NP2T (Tape and Reel)

●

Single chip system for direct quadrature down

conversion from L-band

High signal handling capability for minimum

external component count application, requires

external RF AGC of 30dB

Compatible with DSS and DVB system

requirements

Excellent gain and phase match up to 30MHz

baseband

High output referred linearity for low distortion and

multi channel application

Fully balanced low radiation design

Integral RF AGC amplifier

Two selectable varactor tuned local oscillators

with buffered output for driving external

synthesiser loop

Description

●

TheSL1925isawidebandquadratureconverteroperating

from 950 to 2150 MHz, intended primarily for application

in satellite tuners.

The device contains all elements necessary, with the

exceptionoflocaloscillatorsustainingnetwork,tofabricate

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.

●

ESD protection (Normal ESD handling procedures

should be observed)

The SL1925 is optimised for use with a low phase noise

synthesiser, a range of which are available from Zarlink

Semiconductor. This will form a complete front end tuner

functionfordigitalsatellitereceiversystemsutilisingDSP

derotation recovery.

Applications

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.
