图2-12 完成后的偏执电路原理图(3)执行菜单命令【design guide】点击【amplifier】,弹出放大器设计导向对话框,选择“transistor bias utility”,单击【ok】按钮,弹出“transistor biass utility”对话框,输入前面确定的晶体管直流工作点vdd=3v,vds=2.7v,ids=30ma(注意:atf55143的封装上有两个栅极ids=30ma,相加就是...
目前ADS所提供的设计指南包括:WLAN设计指南、Bluetooth设计指南、CDMA2000设计指南、RF System设计指南、Mixer设计指南、Oscillator设计指南、Passive Circuits设计指南、Phased Locked Loop设计指南、Amplifier设计指南、Filter设计指南等。除了使用ADS软件自带的设计指南外,使用者也可以通过软件中的DesignGuide Developer Studio建立...
This paper presents design of low noise amplifier (LNA) for operating frequency of 9.4 GHz (X-Band) using Advanced Design System (ADS). This LNA uses transistor NE3511S02 from NEC Electronics where it have high gain and super low noise figure. From datasheet this transistor has noise figure...
This paper firstly gives a brief introduction to the relevant basic theories applied in the design of the amplifier,then designs an RF amplifier working in 1.5GHz by the theory of RF circuit and ADS simulation software,and then makes a simulation and optimization to those factors such as the ...
