The UCODE G2iL fully supports all parts of the "Specification for RFID Air Interface
EPCglobal, EPC Radio-Frequency Identity Protocols, Class-1 Generation-2 UHF RFID,
Protocol for Communications at 860 MHz to 960 MHz, Version 1.2.0".
The interrogator provides an RF field that powers the tag, equipped with a UCODE G2iL.
The antenna transforms the impedance of free space to the chip input impedance in order
to get the maximum possible power for the G2iL on the tag. The G2iL+ can also be
supplied externally.
The RF field, which is oscillating on the operating frequency provided by the interrogator,
is rectified to provide a smoothed DC voltage to the analog and digital modules of the IC.
The antenna that is attached to the chip may use a DC connection between the two
antenna pads. Therefore the G2iL also enables loop antenna design. Possible examples
of supported antenna structures can be found in the reference antenna design guide.
An interrogator transmits information to the UCODE G2iL by modulating an UHF RF
signal. The G2iL receives both information and operating energy from this RF signal. Tags
are passive, meaning that they receive all of their operating energy from the interrogator's
RF waveform. In order to further improve the read range the UCODE G2iL+ can be
externally supplied as well so the energy to operate the chip does not need to be
transmitted by the reader.
An interrogator is using a fixed modulation and data rate for the duration of at least one
inventory round. It communicates to the G2iL by modulating an RF carrier using DSB-ASK
with PIE encoding.
For further details refer to
An interrogator receives information from a G2iL by transmitting an unmodulated RF
carrier and listening for a backscattered reply. The G2iL backscatters by switching the
reflection coefficient of its antenna between two states in accordance with the data being
sent. For further details refer to
The UCODE G2iL communicates information by backscatter-modulating the amplitude
and/or phase of the RF carrier. Interrogators shall be capable of demodulating either
demodulation type.
The encoding format, selected in response to interrogator commands, is either FM0
baseband or Miller-modulated subcarrier.
