摘要
介绍了一种在Ka频段具有镜频抑制功能的四次谐波混合集成电路混频器的设计与实现。该混频器主要采用微带混合集成电路,由薄膜陶瓷基片制作。经测试,当中频固定在70 MHz,在射频大于4 GHz带宽内,变频损耗小于11.2 dB,镜频抑制度大于20 dB。
The design and implementation of a Ka - band hybrid integrated sub - harmonic image - rejection mixer is presented. The mixer is fabricated by using HMIC process based on the thin film ceramic sub- strate. The test results show that conversion loss is less than 11.2dB and the image - rejection ratio is more than 20dB over 4GHz RF bandwidth, when IF is fixed at 70 MHz .
