Yuxing Zhang · Modern Electronics Technique · 2009
This paper briefly presents the theories of designing RF Low Noise Amplifiers(LNAs),then analyses the stability of the device ATF-54143 adopted in this design and proposes an effective method to improve it.Methods of analyzing and designing balanced configuration and matching networks of LNA used in receiver front-ends for WCDMA Distributed Base Station(BTS) are expatiated,which is simulated and optimized using Advance Design System(ADS).Practical test and debugging of the product demonstrate that the LNA has great capabilities and works well,and can be applied to multi-band of WCDMA with its all-right general utility.
