X波段宽带固态功率放大模块研究

摘要

Recently, as microwave technology developed rapidly, SSPA(Solid-State Power Amplifier) has been more and more widely used and developed. In this paper, the application of a wide frequency X-band SSPA was presented. Multichip combination and modular technique were adopted in the design of SSPA. To meet the engineering request of the product, output power of the X-band was obtained through the Lange bridge. We simulated program through ADS and HFSS before designing the printed version, and tested every device. The measured results showed a good coincidence between the simulation data and testing data.%近年来,随着微波技术的发展,固态功放得到了越来越广泛的应用,而这方面的技术也发展迅猛,本文介绍了一种X波段宽带固态功率合成放大模块的工程实现.固态功放采用功放芯片合成的方法,并采用模块化设计,为以后更大功率的合成提供最基本的功放单元模块;文章所研究合成功率放大器的基本单元模块由两个功率芯片通过Lange 桥功分/合成器,实现X波段宽带固态功放的实现.在设计版图前通过ADS及HFSS仿真软件进行仿真,并对各独立器件进行测试.最终测试数据和模拟数据基本吻合.
