摘要：

This paper describes a frequency-agile RF front-end in 65nm CMOS targeting short-range full-duplex wireless communication. Complementing previous work on a self-interference cancelling receiver, this work describes the co-integrated transmitter and reports the phase noise advantages of using correlated clock resources to clock all up-and downconverters present in the system. The hardware is capable of frequency-agile operation from 0.15 to 3.5GHz carrier frequency. Measurements at 2.5 GHz indicate that the RX noise floor is only 1 dB degraded by phase noise when operated from a commercial PLL with similar to-38 dBc phase noise.
