We are developing a new instrument, the RF Josephson arbitrary waveform synthesizer (RF-JAWS), for communications metrology and quantum information applications. An important aspect of the RF-JAWS design is the accurate and traceable characterization

Radio-frequency identification (RFID) readers are the main bottleneck when building an RFID system. The cost of the readers can be high, and these devices can be bulky. Moreover, when these RFID readers have to be included in a small mobile device, t

We report on the calibration of quantum-based radio frequency waveforms generated by a Josephson arbitrary waveform synthesizer system. We measure these waveforms using a vector network analyzer and calibrate them at 4 K using a custom-designed cryog

We report on the design of an enhanced EPC Gen2/ISO18000-6C-compliant UHF RFID reader with waveform optimization capability. By properly designing the powering waveform, e.g., a multisine (MS) signal, the power transfer to the transponders is improve

Fully passive wireless networks are a key-enabling technologies for the internet of things. Backscatter radios are a hypothesis to design these passive wireless networks. Backscatter modulation allows a remote device to wirelessly transfer informatio

We propose an approach for characterizing the complex frequency response of sampling oscilloscopes using a calibrated large-signal network analyzer (LSNA) and a broadband pulse source. First, we perform a full wave-parameter calibration of the LSNA u

Passive RF identification (RFID) readers transmit a continuous wave (CW) powering signal to remotely power up batteryless transponders, while simultaneously receiving a backscattered signal at the same frequency [1]. To separate the transmitter and r
