摘要
从微波晶体管、场效应管管芯的单向化模型出发 ,给出了对微波宽带放大器的不等波纹函数型阻抗匹配网络综合方法。对于微波晶体管场效应管的增益随频率“下滑”的现象给出新的更为简单的补偿方法。以HFET- 1 0 0 0管芯为例 ,用不等波纹函数型综合与补偿方法得到的 6GHz～ 1 2 GHz的输入输出阻抗匹配网络与传统的切比雪夫型相比 ,所用的 L、C元件数不足后者的一半且其增益。
The synthesis procedure of the unequiripple function type impedance matching networks is given for the RC series and parallel load. A new and simple synthesis procedure is used to compensate for the gain roll off of the transistor. Taking HFET 1000 chip for example, by using the unequiripple function synthesis procedure, the structure of this network is more simple than that of Chebyshev case, and we may get better gain and stability for this amplifier.
