TRF2443 Integrated IF Transceiver Evaluation Module
This document provides an easy guide for evaluating the TRF2443 integrated IF transceiver for broadband
wireless applications. Included in this guide are equipment setup procedures, software GUI configurations,
and test procedures that allow a user to quickly and accurately measure the TRF2443 performance.
The TRF2443 is a fully integrated IF transceiver operating at a transmitter IF of 340 MHz (or 170 MHz)
and a receiver IF of 140 MHz (or 280MHz). The IF transceiver is used to for up-conversion of signals from
the
transmit
chain
digital-to-analog
convertor
(DAC)
to
the
RF
upconverter
device
and
for
down-conversion of received IF signals to baseband for processing by the analog-to-digital convertor
(ADC). The receiver allows for switching in an external SAW filter if needed or by-passing this filter and
processing the signal completely internally. The TRF2443 also provides an Auxiliary Receiver which can
be used for cross-polarization interference cancellation (XPIC). This document describes how to test the
TRF2443 as well as the many options for trimming the device configuration to meet your application
needs.
