摘要
介绍一种L波段单级高线性低噪声放大器的工作原理和设计方法。与传统的接收机射频前端放大器主要考虑低噪声和高增益特性不同,文中选用了低成本、低功耗的S iGe NPN B JT器件设计高三阶交截点的低噪声放大器。设计中利用了微波CAD工具对电路进行仿真与优化,同时对生成的微带印刷电路板进行了电磁仿真。
Operation principles and design methods of an L-band single-stage high linearity LNA are presented. Different from classical RF front-end receiver designs which mainly considered low noise and high gain, this paper designs a high IP3 LNA through low cost and low power levels SiGe NPN BJT device. With help of microwave CAD, circuit is simulated and optimized, and the microstrip PCB generated is also simulated with the EM methods.
