Texas Instruments Introduces High-Frequency, Multi-Standard RFID Reader Family

Several key performance attributes are built in. For instance, to maximize read-range and reliability, the integrated, on-board linear voltage regulators that turn up the analog, digital and power amplifiers provide power supply noise isolation. The reader has an integrated analog front-end and data framing system for all the supported standards. In addition, the dual receiver input configuration detects amplitude modulation (AM) and phase modulation (PM) to eliminate read “holes” created when antenna orientation in the operating environment changes the tag return signal from AM to PM.
