Baseband Circuits for an RFID Receiver
advertisement Baseband Circuits for an RFID Receiver ā Design Note 381
Radio Frequency Identiļ¬cation (RFID) technology uses
radiated and reļ¬ected RF power to identify and track a
variety of objects. A typical RFID system consists of a
reader and a transponder (or tag). An RFID reader contains an RF transmitter, one or more antennas and an RF
receiver. An RFID tag is simply an uniquely identiļ¬ed IC
with an antenna.
Communication between a reader and a tag is via backscatter reļ¬ection, similar to a radar system, in the UHF
frequencies from 860MHz to 960MHz. This design note
describes a high performance RFID receiver.
A Direct Conversion Receiver
Figure 1 shows the block diagram of a direct conversion
RF receiverāthe receiver demodulates an RF carrier
directly into a baseband signal without an intermediate
frequency down-conversion (a zero IF receiver).
The antenna, shared by both the transmitter and receiver,
detects an RF carrier and passes it through a bandpass
ļ¬lter to an LTĀ® 5516 demodulatorās RF input.
The LT5516 direct conversion demodulator frequency
range of 800MHz to 1.5GHz includes the UHF range used RX
