摘要

我们利用双掺杂AlGaAs/InGaAs/AlGaAs伪晶高电子迁移率晶体管(p-HEMTs)开发了一种用于LiNbO/sub - 3/调制器驱动器(LN驱动器)的共面波导型分布式放大器。通过稳定和阻抗控制技术，我们获得了基片厚度为600 /spl mu/m的共面波导(CPW)线的45 GHz带宽和基片厚度为75 /spl mu/m的接地共面波导(GCPW)线的54 GHz带宽，以及40 Gb/s的6 vp -p线性输出。这些结果表明，我们的电路设计技术适用于光纤通信系统。

45 GHz distributed amplifier with a linear 6-Vp-p output for a 40 Gb/s LiNbO/sub 3/ modulator driver circuit

We developed a coplanar waveguided-type distributed amplifier for a LiNbO/sub 3/ modulator driver (LN driver) using double-doped AlGaAs/InGaAs/AlGaAs-pseudomorphic High Electron Mobility Transistors (p-HEMTs). By using a stabilization and impedance control technique, we obtained a 45 GHz bandwidth for coplanar waveguided (CPW) lines with a 600 /spl mu/m thick substrate and 54 GHz bandwidth for grounded coplanar waveguided (GCPW) lines with a 75 /spl mu/m thick substrate, and a linear 6-Vp-p output at 40 Gb/s. These results indicate that our circuit design technique is suitable for use in fiber-optic communication systems.
