Low-power AS3993 from ams provides UHF Gen 2 RFID reader capability for new handheld computers from Intermec

The benefits of the products include excellent data-capture capabilities and long battery life.



These requirements are perfectly supported by the AS3993, an EPC Class 1 Gen 2 RFID reader designed for mobile, space-constrained or embedded applications. Packaged in a small QFN48 7mm x 7mm package, the device offers impressive radio performance, providing a high 20dBm output power from an internal power amplifier (PA) or highly linear 0dBm output for operation with an external PA. Its selectable sensitivity of -90dBm supports the use of small, embedded antennas while maintaining excellent read capability in the presence of antenna reflections and a self-jammer.



In the AS3993, this high performance is combined with low power consumption and low-voltage operation, helping to extend battery life. Unlike competing UHF RFID readers which implement their protocol handling in digital or software, the AS3993 is an all-analog design that uses far less power than rival DSP-based architectures. Power specifications for the AS3993 include operation at a power supply as low as 2.7V, and a 65mA current requirement.



‘We are excited to work with Intermec because this application pushes the envelope of high performance and low power,’ said Mark Dickson, Senior Marketing Manager (Wireless) at ams. ‘Intermec is an industry leader, and by taking full advantage of the performance benefits of the AS3993, it has created an outstanding new range of handheld computers with RFID capability.’
