This letter discusses the implementation of microwave backscatter links in CMOS technology which are similar to existing systems at mid-UHF for RFID, but intended for use at the 2.4 GHz ISM band towards higher data-rate wireless connectivity solutions. The demonstrated microwave backscatter link uses CMOS RFIC implementation as opposed to discrete components, enabling low power consumption, while maintaining a high modulation bandwidth. Similar to RFID readers, the prototype link also cancels the carrier self-leakage and ambient reflection with internal calibration within a base-station chip. The demonstrated link is implemented and characterized in a 65 nm CMOS technology and is shown to provide 330 Mb/s of raw data-rate with BERs better than}10(-9) over distances up to 2.5 m.
