IN ADDITION TO ITS0.25-m QUBiC4Xi SiGe:C devices, NXP Semiconductors has developed an ultra-high-frequency (UHF) radio-frequencyidentification (RFID) solution for the fashion, retail, and electronics markets. The UCODE G2iL and G2iL+ achieve good read ranges based on a simple, single antenna solution (Fig. 1). In addition, the new chips feature a tag tamper alarm, several privacy-mode options, and password-protected data transfer or digital switch.

"Long read ranges, without the extra cost of a second antenna, and effective privacy protectioncombined with a tag tamper alarmare essential in radio-frequency-identification (RFID) tags and labels for high-volume consumer goods. Through ongoing evaluation and testing in NXP's RFID Application and System Center, we've developed a unique product series that has been optimized for real-life conditions in the retail, fashion, and electronic device markets," comments Chris Feige, NXP's General Manager of Tagging and Authentication.

The NXP UCODE G2iL and G2iL+ chips offer single antenna port sensitivity of -18 dBm. Compared to previous UCODE devices, they claim to require only half the RF power to activate the chip. This aspect results in extended read ranges, which match dual-antenna-port solutions with equal-sized antennas. When it is connected to a power supply, the UCODE G2iL+ further improves both read and write performance to -23 dBm.
