摘　　要：射频放大器是收发信系统中不可缺少的重要器件,文中利用了S IEM EN S公司生产的BFP 420硅双极晶体管,采用三种不同的集电极偏置电流,设计了工作在2.4 GH z的射频放大器,对放大器的稳定度、噪声和线性度进行了详细的分析和比较,利用ADS设计软件设计、仿真和优化了三个放大器,并用微带电路实现,测试结果表明放大器的实测结果与计算和仿真结果基本一致。RF amplifier is the indispensable equipment in the receive-transmit system.Based on Siemens's Si-BJT BFP420,a RF amplifier on 2.4 GHz with three different collector bias currents was designed.The stabilization,noise figure and linearity were analyzed and compared detailedly.ADS was used to design,simulate and optimize the three amplifiers,and a microstrip circuit was employed.The test results prove the accordance between the test and the simulation.
