An Adaptive Analog Temperature-Healing Low-Power 17.7-to-19.2GHz RX Front-End with ±0.005dB/°C

📋 论文概要

该论文提出了一种自适应模拟温度修复的低功耗17.7-19.2GHz接收前端，通过温度补偿技术实现了极小的增益变化（±0.005dB/°C）、噪声系数变化（<1.6dB）和IP1dB变化（<2.2dB），解决了相控阵系统中单元性能不均匀的问题。

💡 主要创新点

• 提出自适应模拟温度补偿架构，无需数字校准即可在全温度范围内稳定接收前端性能。
• 在毫米波频段实现低功耗设计，同时保持极低的增益和噪声系数变化。

To achieve excellent performance, phased arrays require lownoise and high-linearity front-ends [5]. Most importantly, arrays demand uniform performance from all elements for optimum receiving G/T value and transmission effective isotropic radiated power (EIRP) [6]. Figure 14.7.1 exemplifies it with an array whose antenna element has 3dBi uniform gain on one side and no radiation on the other side. When all elements in an 8×1 linear array with a λ/2 space have identical characteristics, the array presents a 19dBi gain in the normal direction. Any temperature
