gaas fet meaning in Chinese

砷化镓场效应晶体管

Through the design the dc feed network , input matching network for the ne900175 gaas fet and analysis the stabilization , power gain , bandwidth of the power amplifier we get the power amplifier is stability , the power gain is 11 . 967db and the bandwidth is 300mhz . microstrip antenna has a narrow bandwidth , in this design antenna ' s bandwidth is 100mhz . antenna is the not only the load of the power amplifier , but also as the filter connecting to the output of the power amplifier
E类功放的pae相对a类、 b类、 ab类的功率放大器类型而言比较高，在50 ? 70 。分析了e类功放的工作过程后，以ne900175的gaas场效应管作为e类功放电路的开关，进行了外围电路的设计，包括直流偏置电路、输入匹配网络的设计，功放的稳定性、带宽、增益的分析。该功放增益最大达到11 . 4db ,带宽为320mhz 。
