Abstract
A tri-mode mixer supporting the 5G NR standards over 24.25--71GHz is presented. The harmonic-selection technique reduces the local oscillator (LO) frequency range and power consumption. Besides, the proposed multiphase LO rejects unwanted harmonics. Fabricated in a 65nm CMOS process, this work consumes 12-21mW power under a 1V supply. It presents more than 20dB rejections to the undesired harmonic components at all operation bands. The required LO frequency range is only 10GHz.Keywords
