摘　　要：射频前端芯片集成了PA、LNA和收发开关电路,实现了无线局域网所需要的射频功能,设计了一个高性能的应用于2.4 GHz无线局域网的低噪声放大器。电路设计全部基于SMIC RF 0.18μm CMOS工艺完成,利用Cadence进行了电路设计和模拟仿真验证,画出了LNA的版图,最终合成了一个整体版图并进行了流片,芯片测试结果良好。The RF front-end chip designed in this paper integrates the PA,LNA,transmit and receive switching circuitry, incorporates all the RF functionality needed for today＇s wireless communications. A 2.4 GHz high performance low noise amplifier for wireless local area network has been implemented in SMIC 0.18 μm CMOS process.Cadence software is used to design and optimize the circuits,and this paper has give out the LNA layout. At last ,a whole layout is achieved and processed by a successful tape-out,and it has a good test result.
