摘要

本文提出了一种多项式拟合的多谐失真(PHD)模型，并用频率自定义器件(FDD)实现该模型。多项式拟合技术通过单组模型参数，提供了包含不同输入功率状态的PHD模型的有效方法。它可以大大降低模型提取的复杂度，并压缩模型文件的大小。本文介绍了PHD模型的基本理论、多项式拟合方法和FDD技术。在测试实例中使用了10w的氮化镓封装晶体管。结果表明，该模型对基频和次谐波行为预测均具有较高的精度。

Implementation of Polynomial Fitted Poly-Harmonic Distortion Model with Frequency Defined Device

In this paper, a polynomial fitted poly-harmonic distortion (PHD) model is proposed, and it is implemented with frequency defined device (FDD). Polynomial fitting technique provides an effective method to including PHD model with different input power states through single set of model parameter. It can greatly reduce the model extraction complexity, and compact the model file size. The basic theory of PHD model, polynomial fitting method, and the FDD technique is provided in this work. A 10 W Gallium Nitride (GaN) packaged transistor is used in the test example. The results show that the proposed model has high accuracy for both fundamental and second harmonic behavioral predictions.
