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.

Features

● 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

● ESD protection (Normal ESD handling procedures

should be observed)

Applications

● Satellite receiver systems

● Data communications systems
