Nowadays the implementation of highly
integrated UHF RFID reader transceiver RF front-ends
with excellent performance is demanding and is still
challenging. This paper presents a number of design
considerations from the system point of view, including
the choice of receiver/transmitter front-end architecture,
isolation between transmitter and receiver, power
efficiency of the transmitter. Some critical system
performance issues like sensitivity, noise figure, dynamic
range and AGC operation, LO phase noise, et al. are also
presented.
