Design Of Continuous High-Efficiency Broadband Linear Power Amplifier Using Two-Tone Signal Analysis
MICROWAVE AND OPTICAL TECHNOLOGY LETTERS(2020)
摘要
In this article, a novel method to design broadband linear power amplifier (BL-PA) is presented. By adding the image parts for harmonics and intermodulation products (HIMPs), a suboptimal solution of efficiency and linearity in continuous frequencies can be achieved at a broadband to improve the efficiency and linearity performance of the BL-PA. For verification, a BL-PA operating 3.2-3.8GHz is designed and the performances are assessed in multi modes.
