Tempe, Ariz.—Anadigm's third-generation RangeMaster5 three-part chipset for RF identification (RFID) allows system vendors to design and maintain a combination HF and UHF reader that can be customized to modulation type and frequency. The product fully supports current HF standards as well as newer standards under study by EPC (Electronic Product Code). As in earlier models, it will support EPC Global Gen 1 and Gen 2 (class 0, 1, 2) protocols for UHF as well as ISO18000-6 standards.
The 3.3-volt chipset comprises two dynamically programmable analog signal processors (dpASP) and an RFID state machine. Thus designers can dynamically switch from HF and UHF baseband frequencies. It can also dynamically switch between protocols and frequencies for optimized RFID tag reading. Its I and Q filtering allows it to be programmed to remove spurs and harmonics. The reader can also be calibrated at the customer site to eliminate background interfrence, such as that caused by fluorescent lighting. The chipset provides anti-saturation control and can extract all data frequencies from DC to 800 kHz, and selected frequencies up to 3.3 MHz.
In the UHF mode, the chipset offers the user a choice of four baseband analog signal processing circuits (universal, EPC Gen 2 twin or triple, and class 0). In the HF mode, designers may select universal or twin-signal processing. Users can select from 16 predefined values of the upper and lower subcarrier frequencies and choose digital or analog outputs. Control is via an SPI interface.
Contact the company directly for complete product specifications. The chipset is priced starting at $17.94 each in 10k sets. Samples are available now. The RangeMaster5 evaluation board is priced at $199.
