Receiver User’s Guide
Abstract
The dual-band handset market is expanding very rapidly due to
the increase in customers requiring roaming capability. The
customer also demands that handsets have an increase in
features while keeping the size compact. These dual-band
handset requirements put pressure on the integrated circuit
manufacturer to be innovative while keeping costs low.
To meet this demand, Texas Instruments (TI) has developed the
TRF1500 receiver. The TRF1500 is a fully-integrated dual-band
receiver in a single package. The selection of the external
components and the layout of the system board required to
complete a transceiver design are critical to achieve maximum
performance.
This application report discusses the implementation and
impedance matching of each section of the TRF1500 to keep the
required board area to a minimum and minimizing external
components while maximizing performance. It also discusses
parameter measurement techniques.
