论文摘要
通信，雷达和电子战接收器的主要挑战之一是附近的设备干扰。本文提供了2-6 GHz GAN LNA前端，并利用基于微控制器的控件进行了板载感应，处理和反馈，以通过功率和线性法规适应各种干扰场景。 GAN LNA的利用可为雷达和EW应用提供高功率处理能力（30 dBM）和高线性（OIP3 = 30 dBm）。该系统允许LNA功率消耗从500 mW到2 W（4倍），以调整从p \ textSubscript {1db，in} = -10.5 dbm至0.5 dbm（> 10倍）的线性。在整个调谐范围内，噪声图增加了约0.4 dB。反馈控制方法具有控制理论的背景。其余的控件消耗$ \ leq $ 10 $ \％$ \％$（100兆瓦）名义LNA功率（1 W），以实现适应时间<1 ms。
One of the major challenges in communication, radar, and electronic warfare receivers arises from nearby device interference. The paper presents a 2-6 GHz GaN LNA front-end with onboard sensing, processing, and feedback utilizing microcontroller-based controls to achieve adaptation to a variety of interference scenarios through power and linearity regulations. The utilization of GaN LNA provides high power handling capability (30 dBm) and high linearity (OIP3= 30 dBm) for radar and EW applications. The system permits an LNA power consumption to tune from 500 mW to 2 W (4X increase) in order to adjust the linearity from P\textsubscript{1dB,IN}=-10.5 dBm to 0.5 dBm (>10X increase). Across the tuning range, the noise figure increases by approximately 0.4 dB. Feedback control methods are presented with backgrounds from control theory. The rest of the controls consume $\leq$10$\%$ (100 mW) of nominal LNA power (1 W) to achieve an adaptation time <1 ms.
