摘要

本文介绍了微波放大器的设计现状和高精度的设计方法。基于矩量法(MoM)数值方法的全波电磁(EM)模拟器与传统的基于spice的微波电路模拟器互补,证明了其在稳定性、回波损耗和小信号增益等方面的优越性能。这种被称为EM/电路联合仿真的方法保证了设计与第一块板带出一起工作,同时避免了多个板布局,这将分别节省设计成本和时间。通过设计一种用于IEEE 802.16e移动WiMAX应用的基于E-pHEMT技术的功率放大器,对该方法进行了精确的验证。

The Emerging Role of EM Simulation in IEEE 802.16e Mobile WiMAX Power Amplifier Design
This paper features state of the art and highly accurate method of designing a microwave amplifier. A Full-wave Electromagnetic (EM) Simulator that is based on Method-of-Moments (MoM) numerical method was used in complement with the conventional SPICE-based microwave circuit simulator to demonstrate a superior performance outcome such as Stability, Return Loss and Small Signal Gain. This method known as EM/Circuit Co-Simulation guarantees a design that work with the first board tape-out and concurrently multiple board layouts are avoided, which will saves design cost and time respectively. The method is precisely demonstrated with the design of power amplifier based on E-pHEMT technology intended for IEEE 802.16e Mobile WiMAX applications.
