RFID Reader Chipset Supports HF, UHF

Combining dynamically programmable, analog signal processor with RFID State Machine, RangeMaster2 allows system vendors to design and maintain single universal reader that can be customized to read different RFID tag types. Operating at 3.3 V, chipset offers choice of Universal, Twin or Triple EPC Gen 2, or Class 0 baseband analog signal processing circuits. It provides anti-saturation control and can extract all data frequencies from DC-800 kHz.

Full Release:

Anadigm (Tempe, Az.) announced the immediate availability of RangeMaster2 - the company's second generation RFID reader 3.3 volt chip set solution that allows system vendors to design and maintain a single "universal" reader that can be customized to read different radio frequency identification (RFID) tag types, with different modulation types and frequencies. RangeMaster family fully supports HF and UHF protocols- EPC Global Gen 1 and Gen 2 (class 0, 1, 2) and ISO18000-6 standards.

RangeMaster2 is a two-chip set comprised of a dynamically programmable analog signal processor (dpASP) in conjunction with an RFID State Machine. This enables system designers to develop a universal RFID tag reader that can support multiple protocols and frequencies for Universal Fixed Readers, Portable/Handheld Readers, Combination Bar Code and RFID Reader/Scanners. By allowing standardization around a single printed circuit board to support multiple end products and markets, RangeMaster2 simplifies and improves product development.

RangeMaster2 operates at 3.3 volts, while providing increased read range and sensitivity optimization with variable gain. As a 3.3 volt chip set, with significantly lower power, it is ideally suited for portable readers as well as fixed based readers. It offers the user a choice of four different baseband analog signal processing circuits: Universal, EPC Gen 2 (Twin or Triple) or Class 0. RangeMaster2 also supports the ability for the user to select from 16 predefined values of the upper and the lower sub-carrier frequencies and choose digital or analog outputs. With its control word access via a serial peripheral interface (SPI), the user has the ability to adjust multiple parameters without disruption to the signal path.

The reader can be calibrated at the customer's site to eliminate background interference, such as that caused by fluorescent lighting. It allows EPC2 frequency pair decoding or selectable single frequency decoding. The chipset also provides anti-saturation control and can extract all data frequencies from DC to 800 kHz, and selected frequencies up to 3.3 MHz.
