该论文针对大规模MIMO和车载雷达等应用对接收机线性度的高要求，提出了一种利用Doherty有源负载调制技术增强毫米波低噪声放大器线性度的新设计。通过该技术，LNA能够在存在强干扰信号时保持信号完整性，有效抑制阻塞效应。
Conventionally, the linearity of receivers (RXs) or low-noise amplifiers (LNAs) has not been a primary design focus, as they are generally optimized for handling weak input signals. However, emerging applications such as massive MIMO (Multiple Input Multiple Output) and automotive radar demand high-linearity RX/LNAs, as each receiving path must manage multiple signals concurrently or detect weak signals in the presence of strong interferers. This shift necessitates RX/LNA designs with superior linearity to preserve signal integrity
