摘要
针对V频段功率放大器工作频段高、电路合成损耗大以及效率低的现状,提出基于波导 E-T结和新型波导魔T的空间功率合成方式,采用模块化设计思路,先将 8 路芯片进行合成形成一个基础单元模块,再将 8 个基础单元模块进一步合成,最终实现了 64 路空间功率合成.在整机结构及热设计上,创新性地采用三明治结构,使设备能够有效散热的同时,减小了整机体积,实现了整机的高集成度设计.经测试,该V频段功率放大器在 47～51 GHz的饱和输出功率高于 500 W,合成效率达到 78.1%.
Abstract
In view of current situation of V-band power amplifier with high operating frequency,large circuit combining loss and low efficiency,modular design is adopted to realize the 64-way spatial power combining based on the combination of the waveguide E-T junction and the new waveguide magic T.First,8 chips are synthesized into a basic unit module,and then 8 basic unit modules are fur-ther synthesized.In the structure and thermal design of the amplifier,an innovative sandwich structure is used,so that the volume of the whole equipment is reduced while the heat dissipation is effective,and the high integration is realized.The tested saturation output power of the amplifier is greater than 500 W at 47～51 GHz,and the combining efficiency is 78.1%.
