This paper presents the design of a high sensitivity low power RFID reader. The reader has good robustness and reliability in multi reader dense environment.
The LTC6602 is a dual, matched, programmable bandpass filter intended to optimize high performance UHF RFID readers. It features two identical filter channels with matched gain control and frequency-controlled lowpass and highpass networks.
The device allows for software definition of the operating mode by controlling the baseband bandwidth. Key specifications include an internal clock frequency positionable between 40MHz and 100MHz via an external DAC, a cutoff range for the highpass filter from 6.7kHz to 100kHz, and a lowpass filter range from 66.7kHz to 1MHz.
The LTC6602 is a dual bandpass filter designed for high performance UHF RFID readers.
The LTC6602 is a very compact IC in a 4mm x 4mm QFN package.
The LTC6602 is programmable with parallel or serial control.
