利用GaN高功率放大器和双四输入圆波导合波器，组装了一个工作在2.1GHz的1kW S波段小型波导合波器。最大功率为200W，采用Peltier器件作为散热器。高功率放大器单元在40摄氏度左右的温度下显示出大于50%的PAE，具有AB类操作。四个GaN高功率放大器与四输入端口圆波导合束器相结合，输出功率为540W。进一步实现了连接两个500W级功率合成器的1kW输出功率。1千瓦级功率合成装置的合成效率达到90%左右。
Using a GaN high power amplifier and a double 4-inputport circular waveguide combiner, a 1kW S-band compact waveguide combiner unit operating at 2.1 GHz was assembled. The maximum power of 200W was realized with a Peltier device for heat sink. The high power amplifier unit shows the PAE of more than 50% with an AB-class operation under the temperature around 40 degrees C. The four GaN high power amplifiers were combined with the 4-inputports circular waveguide combiner, having an output power of 540W. Further the 1kW output power connecting two 500W-class power combiners was achieved. The combining efficiency of the 1kW-class power combiner unit was achieved to about 90 %.
