摘要： In one embodiment, a Radio Frequency Identification (RFID) reader circuit includes a Radio Frequency (RF) source, a RF power amplifier coupled to an output of the RF source in a transmitting path, a first RF bandpass filter coupled between the output of the RF source and a mixer module, and a low noise amplifier in a receiving path being coupled to an input of a second RF bandpass filter. The mixer module receives a signal from the first RF bandpass filter and a signal from the second RF bandpass filter, the mixer module multiplies the signal from the first RF bandpass filter with the signal from the second RF bandpass filter to recover the backscatter sidebands in the signal from the second RF bandpass filter, and the first and second RF bandpass filters provide identical or nearly identical delay of signals. Other systems, methods and circuits are also described.
