TRF1500 Integrated Dual-Band RF 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.
