Description

This application report describes the implementation of multiple reader antennas with a single TRF7970A NFC transceiver IC. For demonstration purposes the MSP430F5529 LaunchPad™ development kit with TRF7970A BoosterPack™ plug-in module are used. The PE42359 UltraCMOS® RF Switch from Peregrine Semiconductors is used for switching due to its simple control methodology and low power loss during swit
