A compact RFID reader platform for UHF and microwave applications.(Cover Feature)

Microwave Journal, April, 2004

A new line of compact RFID readers has been developed for UHF and microwave applications worldwide. WJ's model SX2000 is the first in a series of compact EPC Class 1 RFID readers whose size and performance are enabling new RFID applications. The SX20xx RFID reader platform--only 3.37" X 2.13" X 0.30" and 3 ounces--offers exceptional performance commensurate with much larger units: 1 W max RF output, 14 dB power control range, two separate antenna ports, RS232 or TTL interface protocol, power conditioning and fused over-voltage protection. Table 1 shows the performance specifications for the SX2000. Extensive use of WJ chip sets, novel circuit design and utilization of a cavitized RF web with 0402 passives have enabled the small form-factor.
