摘要

针对低功耗、低失真混频器，提出了一种使用副混频器的三阶互调(IM3)对消技术。该技术在电流增加不到10%的情况下将IM3降低了18dB。混频器的IIP3为10dBm，增益为8.7dB, NF为9.8dB, 2.9V的功耗为30mW。

A +110dBm IIP3 SiGe mixer with IM3 cancellation technique

A 3rd-order intermodulation (IM3) cancellation technique using a sub-mixer is proposed for low-power, low-distortion mixers. The technique reduces IM3 by 18dB with a current increase of less than 10%. The mixer achieves an IIP3 of 10dBm, a gain of 8.7dB, a NF of 9.8dB and dissipates 30mW from 2.9V.
