An 80-GHz low noise amplifier resilient to the TX-spillover in phase-modulated continuous-wave radars

摘要

We propose an 80GHz low noise amplifier capable of linearly handling and canceling a TX spillover up to -20dBm. The cancellation circuit is mainly intended for phase-modulated continuous-wave radar. The circuit is implemented in a 28nm CMOS technology and achieves a gain, NF and iP1dB of 15.2dB, 5.5dB and -15.5dBm respectively, while attenuating the TX spillover by 13.5dB.
