摘要:
基于基片集成波导功分/合成器设计并研制了4路X波段宽带功率合成放大器.功分/合成器由一对4路树状功分器采用背对背方式组成,功分器输入输出端口均包含基片集成波导-微带转接结构,以便于功分/合成器与其他平面器件相连接.在9.3~12.3GHz范围内实测功分/合成器的回波损耗低于-13dB,传输损耗优于-3.3dB.设计并制作了一个X波段4路宽带功率放大器,合成功放在10.4GHz上的1dB压缩点输出功率约为7.1W(连续波工作方式),在8.9~12.3GHz范围内,合成效率大于60%,在9.5GHz上其最大合成效率约为73.6%.测试结果表明,该技术可方便地用于微波与毫米波固态功率放大器设计.
Abstract:
The divider/combiner based on substrate integrated waveguide(SIW)technology is designed and implemented with a double antipodal four-way tree type divider structure. For the purpose of convenient connection with other planar circuits, each port of the divider/combiner is connected with an SIW to microstrip transition. Within the frequency range of 9.3 to 12.3GHz, the measured return loss is below -13dB and transmission loss is better than -3.3dB. A four-way power amplifier at X-band is designed, fabricated and measured in succession. Measured results show that the combined output power at 1 dB compression is about 7.1W(continuous wave)at 10.4GHz. The power combining efficiency is higher than 60% over the interested frequency range of 8.9 to 12.3GHz and it can reach 73.6% at 9.5GHz. The results demonstrate that this technique can be applied to microwave and millimeter-wave power combining with solid-state power amplifiers.
