📋 论文概要

该论文提出了一种工作在2-4GHz频段的抗谐波接收机，通过在天线和基带同时集成谐波抑制机制，有效抑制带内三次和五次谐波干扰，实现了+14dBm和+16.5dBm的谐波B1dB线性度指标。解决了宽调谐接收机中谐波抑制的难题。

💡 主要创新点

• 在天线端内置谐波抑制结构，实现早期谐波滤除，降低后续电路线性度要求。
• 在基带采用谐波抑制技术，与天线端协同工作，进一步提升对三次和五次谐波的抑制能力。
• 实现了极高的三次和五次带内谐波B1dB（+14/+16.5dBm），显著优于传统接收机。

📄 原文摘要

Widely tunable and reconfigurable receivers are heavily in demand both for highperformance and low-power applications such as 5G New Radio and IoT. One of the crucial features required for a widely tunable RX is the ability to suppress harmonic blockers efficiently and at the earliest opportunity. Methods to achieve harmonic rejection (HR) can be categorized into two groups of active and passive HR (Fig. 5.2.1). Many active approaches have been introduced based on weighted recombination at the baseband (BB) [1] or at a preliminary stage employing multi-input multi-output HR-TIAs
