摘　　要：采用MHVIC2115器件设计一个WCDMA驱动级放大器。采用S1P数据模型对输出匹配电路进行仿真设计,解决了器件电路模型无法获取问题。通过添加电位器,减少栅极偏置电路供电端口,方便下一步测试。对于底面源极接地,采用金属支座来承载器件,而非通过焊盘上的过孔来接地。该方法既改善了源极的导电、导热性,又方便了器件的安装固定。This paper designs a WCDMA drive power amplifiers using MHVIC2115 device. Because there is no circuit model about this device,SIP data model is used to simulate the output match circuit. By adding potentiometers,it can reduce power supply ports of the gate bias circuit and facilitate the following measurement. In order to ground backside source terminal of the device,this paper doesn＇t use the grounding holes on the pad, but uses a metal pedestal. This method improves the electrical conductivity, thermal conductivity of the backside source terminal and makes the device installing more convenient.
