摘　　要： 基于实频法思想设计了Ka波段薄膜匹配负载的宽带匹配网络,并利用ADS和HFSS软件进行了仿真和优化。仿真结果表明,在32 GHz～40 GHz频率范围内,所设计匹配负载的电压驻波比均小于1.2。利用丝网印刷以及直流磁控溅射工艺制备了所设计的薄膜匹配负载。测试结果表明,所制备的TaN薄膜匹配负载在30.3 GHz～37.4 GHz频率范围内,其电压驻波比均小于1.3。 A Ka-band thin film termination with broadband matching network had been designed by real frequency method. The microwave characteristics of the thin film termination had been simulated and optimized in ADS and HFSS software. The simulation results show that the VSWR of the film termination is less that 1.2 at the frequency range of 32 GHz -40 GHz. The designed termination was fabricated by screen printing method and DC magnetron sputtering. The experimental results show that the VSWR of the fabricated termination is less than 1. 3 at the frequency range of 30.3 GHz - 37.4 GHz.
