The Design of LNA Based on BJT Working on 2.2-2.6GHz

摘要：

In order to accelerate the design and production of LNA, we can use an EDA tool software to simulate and design it. In this paper, we firstly describe its design principles, steps, functions and key performance indicators. Then we design a LNA with the BJT working on 2.2-2.6GHz(its centrefrequency is 2.4GHz) and simulate its various parameters. At last we obtain the simulation results and the final design of the circuit The results of simulation show that the amplifiers gain is greater than 1OdB, its input and output VSWR are about 1.5dB and its noise figure is about 2 dB in the centre frequency. In the working frequency, this LNA is stable.
